ADVISORY: Washington Road Bridge Replacement Project (last updated 7/27/2023)
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
  • Estimated Duration – 4 months.

Towpath Reroute: 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.
Canal Closure/Reroute: 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.
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.

D&R Canal State Park Overview

Delaware and Raritan (D&R) Canal State Park is a linear park that’s more than 70 miles long and is central New Jersey's most popular recreational corridor.

When it opened in 1834, the Delaware and Raritan Canal provided a direct transportation link between the cities of Philadelphia and New York City. This new transportation corridor was a waterway connection that flowed through the heart of central New Jersey. What was once a thoroughfare for mule-powered canal boats, steam-powered vessels and pleasure boats of all kinds, is today a linear state park that offers a serene and surprising respite from the commotion of nearby highways and surrounding suburban communities. With more than 70 miles of flat, continuous path available for use, the D&R Canal State Park is a haven for cyclists, runners, hikers, nature and history lovers of all kinds.

D&R Canal Brochure

The New Jersey Department of Environmental Protection, Division of Parks and Forestry, State Park Service owns and manages the Delaware and Raritan (D&R) Canal and towpath as a state park. The D&R Canal Commission, legislated in 1974, assists with the development of the park and regulates land use in the park's 400-square-mile watershed. The New Jersey Water Supply Authority operates and maintains the water transmission complex of the canal as a water supply resource, pumping out about 75 million gallons of water a day.

With its wood bridges, lock and bridge tender houses, locks, cobblestone spillways, stone-arched culverts, and historic towpath, the canal is a tremendous attraction for history lovers. Much of the canal system remains intact today and is a reminder of the days when the delivery of freight depended upon a team of sturdy mules or steam-powered vessels. Nearly 36 miles of the main canal and 22 miles of the feeder canal still exist, with many historic structures still standing.

The feeder canal wanders through quaint New Jersey towns along the Delaware River such as Stockton, Lambertville and Titusville and flows past Washington Crossing State Park on its way further south into Trenton. The main canal passes through the heart of central New Jersey from Bordentown to Trenton and further north into Lawrenceville past the Port Mercer bridge tender house, along the outskirts of Princeton, then through the charming villages of Kingston, Griggstown, Blackwells Mills and East Millstone and eventually ending at Landing Lane in New Brunswick. Perhaps the best way to experience the historic canal is on the water; canoes and kayaks can be rented from private concessionaires in the spring through the early fall at Griggstown and Princeton.

The D&R Story
During the early nineteenth century, canals were built as transportation routes to link manufacturing centers and markets. The Delaware and Raritan (D&R) Canal was constructed across central New Jersey to provide an efficient route for transporting freight between Philadelphia and New York City. The two cities selected as the canal’s two terminuses were Bordentown on the Delaware River and New Brunswick on the Raritan River. Water is still supplied to the main canal via a 22-mile-long feeder canal that was dug adjacent to the Delaware River beginning at Bulls Island and continuing south into Trenton. Construction of the D&R Canal began in 1831.

Many skilled men became section contractors and builders while the arduous tasks of ditch digging, earth moving, and tree removal fell to scores of unskilled local men. This local workforce was supplemented in large numbers by migratory and immigrant laborers from Ireland. Originally the main canal was 44 miles long and the feeder canal was 22 miles long, 60 feet wide and 6 feet deep. The entire canal system was completed in June of 1834 at an estimated cost of $2,830,000. Initially, canal boats were pulled exclusively by mule teams but by 1843, steam-powered vessels were in use. These faster, modern boats plied the waters alongside the mainstay mule-powered boats into the early 20th century. To reduce damage to the banks of the canal and its towpath caused by these more powerful vessels, a speed limit of 4 miles per hour was enforced.

The D&R Feeder Canal
Originally designed as a water supply for the main canal, the feeder canal was navigated by vessels from the time of its completion. In 1847, changes were made to allow canal boats from Pennsylvania’s Delaware Division Canal access to the D&R feeder canal at Lambertville. This shortened the journey for boats transporting coal from Pennsylvania to New York City. In 1850, construction of a rail line began along the feeder canal when the Belvidere-Delaware Railroad began laying track on the waterway’s original towpath. Regular rail service opened alongside the D&R feeder canal by 1854.

Decline of the Canal
For nearly a century, the D&R Canal was one of America’s busiest navigation canals. Inevitably the speed and efficiency of railroads overtook the slower pace of canals. The D&R Canal’s last year of operating at a profit was 1892 but it remained open through the 1932 shipping season. After closing, the canal sat unused for several years. In 1936, ownership was turned over to the State of New Jersey. In the 1940s, work to repurpose the D&R Canal as a water supply began. From the 1930s to the 1970s, the D&R Canal transitioned from a working canal to a linear park. Due to a strong grassroots effort to preserve the waterway from encroachment, pollution and development, the canal and its remaining structures were entered on the National Register of Historic Places in 1973. A year later, over 60 miles of the canal and a narrow strip of land on both banks were made an official state park. A portion of the Belvidere-Delaware Railroad corridor from Bulls Island to Frenchtown was added to the park in the 1980s. Click here for a more detailed history of the D&R Canal.

Abbott Marshlands, Burlington and Mercer Counties
Covering more than 3,000 acres of upland forests, tidal waterways and wetlands, Abbott Marshlands is an oasis of natural beauty. The beginning of the D&R Canal at Lock 1 in Bordentown can be found near the convergence of Crosswicks Creek and the Delaware River. What was once a bustling hub of commerce at the start of the canal along the Delaware River and Crosswicks Creek is now a quiet place to explore stands of wild rice and a chorus of bird songs. A 3.5-mile-long trail is accessible from the 295 Scenic Overlook, the pedestrian bridge next to the NJ Light Rail in Bordentown City or a parking area located along Route 129 in Trenton. A network of trails within Abbott Marshlands are maintained by local government and nonprofit agencies. To learn more please visit:

Six Mile Run, Franklin Township, Somerset County
In the late 1950s, it was determined that additional water supply resources were needed for the state of New Jersey. The area around the Six Mile Run creek was identified as a possible location for such a site. In a process that took place over several years in the 1960s, properties were acquired by the state for the purpose of creating an additional water resource in central New Jersey. To that end in 1970, the area was put under the jurisdiction of the N.J. Department of Environmental Protection’s Division of Water Resources with the intent to develop it as a reservoir site. However, by 1993, alternative and adequate water sources had been identified and the Six Mile Run Reservoir project was shelved. No longer immediately needed, the administration of the newly-acquired properties at Six Mile Run was transferred to the Division of Parks and Forestry. Trail systems through former farmlands were soon created.

Today, the Six Mile Run Reservoir Site provides an essential area to enjoy the outdoors with hiking, biking, horseback riding and hunting opportunities. The trail network provides visitors a glimpse into the region’s rich cultural history. The area was listed on the 1995 National Historic Register and is the largest agricultural district in New Jersey. Trail users can see the remains of 18th and 19th century farmhouses, Dutch-framed barns, windmills and silos that hint at the story of the early colonial settlers who inhabited the area in the 1700s while they enjoy preserved open vistas of undeveloped land in the heart of central New Jersey.
