PROJECT UPDATE:
SEPTEMBER 17, 2024
JUNE 11, 2024
BE ADVISED: The New Jersey Water Supply Authority
is doing a rehabilitation of the Six Mile Run Culvert that carries the Six Mile Run under Canal Road and the multi-use trail (towpath) in the vicinity of the Blackwells Mills Causeway in Franklin Township. This project will address past repairs on the culvert and prevent future deterioration of the structure.
The multi-use trail will be CLOSED to the public at the culvert at times (to be determined) during construction but will be re-open on the weekends whenever it can be done safely. Multi-use trail closures will be kept to the minimum duration and intervals to safely complete the project. The project started on August 21, 2023, paused in January 2024, and is set to resume June 12, 2024, for approximately one week.
Starting on June 12, 2024, and lasting about 1 week, the multi-use trail will be closed during construction times, 7:00 AM – 3:30 PM, weekdays, at Six Mile Run Culvert. Signs will be posted at Blackwells Mills Causeway and Griggstown Causeway access points. The multi-use trail will be open outside of these times.
Remaining Project work will resume in July 2024.
PROJECT UPDATE:
Remaining work is as follows: mortar re-pointing and retaining wall reconstruction on the outlet of the culvert, additional clay liner repairs, minor regrading of the Canal embankment, and restoration of the towpath and inlet area. WORK IS ANTICIPATED TO BE COMPLETED IN SUMMER 2024.
Canal Road is currently open. Short term road closures may be required as the project nears completion.
The project will require the closing of the multi-use trail while the work is taking place. Trail closures are expected from Mid June to end of August of 2024. Signage will be posted regarding trail closures as needed.
The project is designed to provide a robust yet historically appropriate repair that serves the varying needs of the public. The goal of this undertaking is to preserve both the structural integrity and historic character of the culvert.
We thank you for your patience as this work progresses.
This project will be managed by the New Jersey Water Supply Authority, a state agency that operates the D&R Canal as a public water supply source for central New Jersey.

Please be advised, the State Park Service would like to clarify information regarding the existing/official trail network at the Six Mile Run Reservoir Site. Although several social/unofficial trails have popped up over the years, we would like to encourage park users to stay on marked/official trails as designated by the State Park Service and shown on the park map below.
As no authorized trail network has formally been established, approved, and/or is maintained in the area south of the Six Mile Run and west of the Creek Trail (Red Trail), we ask that park users avoid this area. Years of unauthorized trail use here has caused damage and erosion to the natural and historic resources at this location.
We ask our park users to set a good example for other visitors today and every day; stay on designated trails!
For more information, please call the D&R Canal State Park office at (609) 924-5705.
UNAUTHORIZED AREA NOTICE:

Due to on-going construction activities by the NJDOT at the Washington Road Bridge Replacement Project, the following-hard closure (i.e., no re-route available) will be in-place starting MONDAY, APRIL 29 extending through FRIDAY, MAY 10, 2024.
The D&R Canal Multi-Use Trail will be closed between the Alexander Road and Lower Harrison Street access points in Princeton NJ.
We would like to ask that the public avoid this section of the towpath during this time. For more information, please call the D&R Canal State Park office at (609) 924-5705 or the Bulls Island office at (609) 397-2949.
The New Jersey Department of Transportation (NJDOT) is initiating the replacement of the Washington Road Bridge over the D&R Canal in Princeton, New Jersey. This project will address structural concerns with the original bridge via construction of a replacement structure.
PROJECT START DATE – JULY 28, 2023
TOWPATH REROUTE:
Canal Closure/Reroute:
However, floating docks will be installed to the north and south of the bridge directly adjacent to the pedestrian towpath which can be utilized as a portage (i.e., take-in/take-out points). Canal users will need to utilize these take-out points, walk along the above-referenced towpath reroute, and utilize the applicable put-in location.
This is a necessary bridge repair/replacement. We apologize for the temporary inconvenience to our park visitors and thank everyone for their patience and cooperation during the duration of the project.
CONSTRUCTION UPDATE:
SOUTHBOUND: The towpath will be closed starting at the Lower Harrison Street Parking Lot/access point.
NORTHBOUND: The towpath will be closed starting at the Alexander Road Parking Lot/access point.
BE ADVISED:
ESTIMATED DURATION – 4 MONTHS.
Due to the construction activities, the towpath in the immediate vicinity of the Washington Road Bridge will be closed; however, a reroute of the pedestrian towpath will be available for the full duration of construction. From the tow path, pedestrians will be guided northwest along the sidewalk of Washington Road (approx. 185 ft.), crossover through a pathway, and head southwest to the desired towpath entrance.
Due to the consistent presence of overhead hazards, narrow canal path below the existing bridge, and demolition of the existing bridge, waterway access to the canal in the vicinity of the bridge will be closed for the duration of the project.

CLOSURE UPDATES:
The D&R Canal towpath is currently closed in Franklin Township between Route 27 at Kingston to Route 518 in Rocky Hill due to significant path erosion and washouts.
The New Jersey State Park Service and New Jersey Water Supply Authority are currently evaluating this section of the path and working towards a repair. An alternate path along the berm side (opposite the towpath) has been cleared and is available for use between Routes 27 and 518. We ask that the public avoid the towpath in this area and instead use the opposite side path during this time.
January 10, 2024
BE ADVISED:
Due to heavy rain, wind and snow melt from the most recent storm, the Millstone and Raritan Rivers rose to flood stage. Both rivers crested late Wednesday, January 10th and water levels slowly receded over the following few days (barring any further rain).
Portions of the towpath from the Millstone Aqueduct in Plainsboro Township to Landing Lane in Franklin Township/New Brunswick were inundated with water. Locations in Princeton Township were also effected. Due to these flood impacts, expect that areas of the D&R Canal State Park towpath may be impassable and/or hazardous. Park users may encounter washed-out areas, debris and/or uneven, muddy surface conditions. We recommend avoidance of these areas.
Please be aware that our maintenance crews will be assessing these impacts in coming week as the flood waters recede. We ask that the public to exercise caution and avoid impacted areas of the the towpath during this time. As always, we appreciate your cooperation, patience and good judgement!
To report specific areas of concern, downed trees or path obstructions, please call the Park Office at 609-924-5705 or email This email address is being protected from spambots. You need JavaScript enabled to view it..

It's official, Central New Jersey is “a thing!” At the end of June the New Jersey legislature (both the Assembly and Senate) signed legislation (S3206/A4711 - still to be approved by the Governor) recognizing the region and defining it as being “comprised, at a minimum of the counties of Hunterdon, Mercer, Middlesex, and Somerset.”
In celebration of this state recognition, Old York Cellars has partnered with Discover Central New Jersey to create a line of wines aptly named “Central Jersey Exists.” How does this connect to the D&R Canal State Park? In support of the park, which runs through all the identified central NJ counties, Old York Cellars has pledged to donate $2 for each bottle sold to two of our partner organizations; the D&R Canal Watch and the Millstone Valley Preservation Coalition/Millstone Valley Scenic Byway. Both not only support the Park but are are actively engaged in resource preservation and the promotion of heritage tourism in Central New Jersey.
So head over to Old York Cellars in Ringoes to purchase a bottle or two and raise a glass to Central New Jersey! This is also a fantastic way for you to help support both our affiliated organizations AND the Park! Thank you Discover Central New Jersey and Old York Cellars. Salute!

The park is happy to report on the completion of another much needed building improvement. With funding from from the
Canal Society of New Jersey and in partnership with the Kingston Historical Society, the historic toll house in Kingston has received new roofing and a new entrance door. Both were much needed and will help to maintain the structure until additional restoration work can be done. We are particularly pleased to see a more historically accurate, period appropriate plank door restored to the structure.
The park again extends its thanks and gratitude to Canal Society of NJ, the Kingston Historical Society and especially to Chris Riley whose expertise, workmanship and cooperation resulted in a fantastic finished product. We are beyond pleased and hope to see additional improvement to this significant piece of D&R history. This toll house/bridge tender’s station is one of five surviving such stations along the corridor.
We never tire of saying that it is partly with the help and support of our partner organizations that much needed projects such as this can be addressed. We are grateful for their willingness to help fund such projects and for their commitment to support the park’s mission of resource stewardship.

Park visitors who explore the trail at Bordentown will notice two new interpretive waysides at the outlet lock area. The park has the Delaware & Raritan Canal Commission to thank for this welcome addition to the park. These waysides provide information about the surviving untouched lift lock located at this entrance point along the former transportation corridor and the small but thriving community that was located here.
The signs were created by Hunter Research in consultation with our park historian. We thank not only the Commission for negotiating for this mitigation project with Jeffery Haberman of Dynamic Engineering Consultants but also the staff at Hunter Research including Patrick Harshbarger who assisted with the content, layout and design as well as Micheal Brown who handled the installation.
If you haven’t visited this area of the park consider a day trip to the historic town of Bordentown. After some sightseeing and perhaps a meal, take a walk over the NJ Transit River Line pedestrian bridge which crosses the Crosswicks Creek to access this section of the D&R Canal State Park for a walk along the towpath!

The Kingston Canal House (a former bridge & lock house) has had a much needed “maintenance makeover.” With funding from from the Canal Society of New Jersey and in partnership with the Kingston Historical Society, the side entrance door was replaced in kind, a new gutter was installed and the entire water damaged facade received several much needed fresh coats of paint. The park extends its thanks and gratitude to Canal Society of NJ, the Kingston Historical Society and Chris Riley who did a fantastic job on the repairs and “facelift” for this historic canal house.
It is partly with the help and support of our partner organizations that much needed projects such as this can be addressed.

It is with a heavy heart that the staff at D&R Canal State Park announces the impending departure of Superintendent Patricia Kallesser; her final day as supervisor will be March 31st. After a tenure of sixteen years with the park, she will be handing the reins over to the next Superintendent tasked to lead the team here. Lauren Rojewski, relatively new to NJ State Parks, and formerly of Spruce Run Reservoir Recreation Area, will step into the Superintendent position at D&R on April 1st. She has big shoes to fill! We all look forward to working with her - WELCOME SUPERINTENDENT ROJEWSKI!
Superintendent Kallesser has led the charge at D&R for the past sixteen years with enthusiasm, a keen sense of dedication, patience and flexibility. She has been an effective and successful multi-tasking project manager who worked every day in cooperation with our partner agencies, friend organizations and volunteers as well as the many municipal and county departments that interconnect/interact with the park.
Overseeing this 70+ mile linear park and the additional properties under the D&R Canal State Park’s management is no simple task. Managing a complicated park such as this can quickly become overwhelming with the many ongoing multi-agency projects, daily maintenance concerns and unexpected issues that often surface especially those repeated flood events. And yet, Superintendent Kallesser stepped-up to that challenge and always attempted to handle the load with professionalism, quick action when needed, attention to detail and thoughtful consideration.
Although the staff is sad to see Superintendent Kallesser move on, we certainly wish her well as she continues her career with NJ State Parks first at Round Valley Recreation Area this spring and summer and then at Spruce Run Recreation Area.
GOOD LUCK Patricia. We all thank you. Congratulations for a job well done! You will be missed but not forgotten and will forever be a part of the D&R Canal legacy!

OCTOBER 26, 2022:
Tree management is an important element of routine maintenance, especially considering the age of
the Canal (hand dug in the 1830’s) and its earthen embankment and clay bottom construction. Tree
maintenance activities include removing fallen trees from the Canal and cutting trees that have rooted
in structures. Trees that have rooted in structures pose a threat to the integrity and stability of the
structures including the embankment itself, retaining walls, spillways, waste gates, culverts, aqueducts,
and other flow control structures. Additionally, trees are trimmed along the towpath to allow for the
safe passage of the general public and for the vehicles that the Authority and the D&R Canal State Park
Service need to maintain the canal and towpath.
Why does the Authority cut down trees along the Canal if they aren’t diseased or dead?
Tree root systems threaten the structural integrity of the Canal and therefore the Authority’s ability to deliver water. Tree roots loosen embankment soils and create seepage paths for water. Seepage paths can develop quickly into large leaks or breaches of the embankments.
The larger the trees become, the bigger the threat they pose. Large trees can be uprooted during
windstorms, which can displace a large amount of soil, making the embankment vulnerable to
breaching. A breach in the embankment impacts the Authority’s ability to deliver water downstream in the Canal.
Tree roots also damage the historic structures of the canal. For example, in many areas the historic stone armoring of the Canal has been lost due to tree roots dislodging stones. These stone structures were constructed to protect the embankments.
One of many examples of damage caused by trees occurred in recent years in Lambertville on the multi-use trail directly adjacent to "It’s Nutts On the Canal" (formerly Lilly’s on the Canal), where several trees fell into the canal and collapsed a retaining wall. The cost to repair that wall was more than $280,000.
More than 1,000,000 people rely on the canal for water and the Authority is obligated to move an
average of 100 million gallons per day of water through it, as measured at Port Mercer. The Authority must take every reasonable measure to properly maintain the canal’s infrastructure in order to protect
our ability to continue to deliver water through it.
SEPTEMBER 10, 2022:
A very grateful thank you to the dedicated D&R Canal Watch volunteers who took on the task of retrieving, repairing, replacing and/or rebuilding several boat access docks that were either damaged or swept away by Tropical Storm Ida over a year ago. A special "shout out" to Watch members Bob Barth, Chuck Martin, Tim Roth, Ted Chase and Wayne Petko who not only gave their time, expertise and sweat equity but also managed the project and helped with the acquisition by The Watch of all the needed materials to see it through.
It has taken time for the Park to comeback from, and address, much of the damage caused by Ida (some projects are still ongoing) but the task has been made just a bit easier with the support of our most dedicated volunteers! Not only did they assist with some of the immediate after storm clean-up, but thanks to their continued efforts, the docks at Kingston, Rocky Hill, Griggstown and Blackwells Mills are now back in service and can be used by all our park users. THANK YOU to the D&R Canal Watch and the "Wednesday Work Crew" volunteers!

Some of our park visitors may have noticed construction on a small structure next to the canal and bridge tender’s house in East Millstone. What looks at first glance like an unimportant small outdoor shed is actually a reconstruction of East Millstone’s historic bridge tender’s station - one of five similar surviving buildings that once served the needs of the tenders who operated the swing bridges at their assigned locations. This station was literally “hanging on the edge,” clinging to the side of the eroding canal bank - a victim of the passing years and continual flooding events. Thanks to the dogged support of the D&R Canal Watch, starting funds were raised and then supplemented in large measure by the D&R Canal Commission paving the way for the project to begin. Pieces of the historic station that could be salvaged and reused were carefully removed, saved and then used in the reconstruction of this small, but significant, piece of D&R history. An idea that began years ago is at long last underway! We are grateful to the staunch support of our partners at the D&R Canal Commission, D&R Canal Watch, HMR Architects, Hawley Brothers and our colleagues at the NJ State Historic Preservation Office and Office of Resource Development who all helped make this preservation effort a reality. Successful preservation projects DO take a village!
UPDATED: JANUARY 19, 2022

Christmas arrived early for this historian and it arrived in the form of a question. Can you identify the location captured in this photograph? Such inquiries make to my inbox from time to time but this one was especially exciting because it involved an interesting backstory attached to a great photograph.
The request came from a gentleman in California who attended graduate school at Rutgers in the 1970s. While there he had purchased a box of unidentified glass plate negatives at an antique shop. The collection had no provenance; just a box of discarded and forgotten images. As a photographer himself, he felt compelled to acquire the entire set. Slowly, over a period of years, he carefully digitized all the plates and began the laborious process of researching. During COVID, with time on his hands and with a need for a good project, he went on a deep-dive journey of discovery that led him to late nineteenth/early twentieth century New Brunswick, early photography and photographers, and eventually to 238 George Street; the home, he would come to learn, of the Howell family. And that’s where the story became especially interesting.
The Howell household included three unmarried sisters - Alice/Allie, Nettie and Margaret/Maggie. It seemed likely that one of these three sisters was the photographer behind the lens that captured their 19th-20th century lives in New Brunswick. A bit of digging revealed that two of the sisters died in the early twentieth century - Maggie in 1911 at 34 years old and Nellie in 1914 at 40 years old. Their deaths roughly coincided with the time frame of the collection of images which spanned from about the 1890s to the early 1900s which seems to suggest that either Maggie or Nellie was the unidentified photographer. The remaining sister, Alice, never married, continued to reside at 238 George Street with her brothers William and Charles and sister-in-law Anna, and passed away in the 1950s. The collection of glass plates were likely stored away in the house and forgotten. In time the home was sold and with no living descendants to claim this collection (another story) the box made its way to an antique shop in town and eventually into the hands of John Cruz. Not seen in many, many years, the collection revealed historic images of turn-of the century New Brunswick. Mr. Cruz went about the task of identifying locations, researching the family and learning about early photography and cameras. In an unselfish act of generosity, he donated this treasure of glass plates to the New Brunswick Public Library where they now safely reside. Thank you Mr. Cruz, you are a preservation hero!
Included in the collection was a photograph that baffled him - the one seen on the bottom half of the comparison image here. He couldn’t place it. He thought it might be Landing Lane in New Brunswick since the majority of images were taken in and around the city but it didn’t quite match. He cast out a net in an effort to locate someone who might be able help identify the canal house captured by the Howell lens around the turn of the century. That inquiry eventually landed in my inbox. I was excited; it was without doubt a fantastic, newly uncovered, photograph of a D&R Canal bridge house but…which one? Without question, it was not Landing Lane! Although some features stumped me, my initial instinct was that this was the bridge house that once stood at what is now Route 518 in Rocky Hill. Two things stood out - the “Look Out For The Locomotive” sign (indicating the presence of a railroad connection) and the distinct curve of the approaching dirt road towards the bridge. It was the road that stood out and was so familiar to me. With a bit of digging I located an identified photograph from the collection of the Rocky Hill Community Group that captured that same distinctive curved road and the “Lookout for the Locomotive” sign - a match! The A-Frame swing bridge had been replaced by a Kingpost, but this was Rocky Hill.
And thus my early holiday surprise! A perfect gift for the historian in your life! So look in those attics, basements and stored away boxes…you never know what treasures from the past might be revealed or photographs of our canal are packed away. My inbox is always open! Happy Holidays everyone!

We are so happy to share the news that the long-awaited shared-use path connecting New Jersey's D&R Canal State Park to Pennsylvania's Delaware Canal State Park at Scudder Falls is NOW OPEN!
The Delaware River Joint Toll Bridge Commission formally opened the crossing during a well-attended public ribbon-cutting ceremony. The ceremonial ribbon was cut by Anne Scudder Smith, ninth-generation descendant of early Ewing Township settler Richard Betts Scudder and the granddaughter of John Montgomery Scott who cut the opening-day ribbon on the first Scudder Falls Bridge in June 1961.
The new river link makes Scudder Falls the only river crossing allowing bicyclists to pedal across without dismounting their bikes.
John Cecil, the Director of the Division of Parks and Forestry, gave remarks at the opening ceremony on the importance of this new connection.
The New Jersey Department of Environmental Protection's Historic Preservation Office, Green Acres Program, and Division of Parks and Forestry were integral in the planning and coordination of this project with the New Jersey Department of Transportation and the Joint Toll Bridge Commission.
We are pleased to add this new loop trail crossing the Delaware River to the five others that link the D&R Canal State Park to the Delaware Canal State Park! Use it well and ENJOY!
