The Delaware and Raritan Canal (D&R Canal) is a canal in central New Jersey, United States, built in the 1830s that served to connect the Delaware River to the Raritan River. It was intended as an efficient and reliable means of transportation of freight between Philadelphia, Pennsylvania and New York City, especially coal from the anthracite coal fields in eastern Pennsylvania. Before the advent of the railroads, the canal allowed shippers to cut many miles off the route from the Pennsylvania coal fields, down the Delaware, around Cape May, and up along the (occasionally treacherous) Atlantic Ocean coast to New York City.

[edit] Route
The main section of the canal is situated between Bordentown on the Delaware and New Brunswick on the Raritan; a feeder canal section (which feeds water into the main canal) stretches 22 miles (35 km) northward from Trenton, upstream along the east bank of the Delaware to Bull's Island near Frenchtown. The feeder canal is used to feed water from the higher elevations to the north into the highest section of the main canal. The total length of the entire canal system was approximately 66 miles (106 km). The main section was 44 miles (71 km) long, 75 feet (23 m) wide and 8 feet (2.4 m) deep; the feeder was 22 miles (35 km) long, 60 feet (18 m) wide and 6 feet (2 m) deep.
[edit] Abandoned Sections
A brief section of the main D&R Canal in Trenton, along Mulberry Street, has been filled in and redeveloped and is inaccessabile to public use. Another section south of Trenton, in the portion of the canal that provided access to the Delaware River in Bordentown is also abandoned, but has not been redeveloped. This section is located in Hamilton Township, New Jersey between the southern boundary of Trenton and the Crosswicks Creek. [1]
[edit] Locks
Locks were used to overcome elevation differences along the D&R canal. Many of the locks are still present along the canal route; however, the lock gates have been replaced on the upstream side with small dams and water outfalls. The downstream gates have been removed, so the water in the locks is level with the water on the downstream side. Some of the locks have been buried or removed due to construction projects that have occurred in the vicinity of the canal.
[edit] Spillways
A number of spillways, which allow overflow water to flow from the canal into nearbay waterways during periods of heavy flow, are located along the canal route. The spillways are evident as a dip in the tow path along the canal. The spillways are stagnant and do not flow in a direction, so numerous fauna inhabit them.
[edit] Construction
The canal system was dug mostly by hand, mostly by Irish immigrants. Work began in 1830 and was completed in 1834, at an estimated cost of $2,830,000. When the canal first opened, teams of mules were used to tow canal boats through it (the steam engine had not yet been introduced). The first steam ships were employed circa 1843.
The canal's greatest usage occurred during the 1860's and 1870's, when it was used primarily to transport coal from Pennsylvania to New York City, which had entered the Industrial Revolution. On May 18, 1872, the D&R Canal Company was merged with several parallel railroads into the United New Jersey Railroad and Canal Company, and leased by the Pennsylvania Railroad. Over time, the importance of the D&R Canal waned as railroads were used to perform, more rapidly, the same function as canals, but it remained in operation until 1932. Years later, the section between Trenton and Bordentown was filled for various road and rail projects, leaving the feeder waters to solely supply the main canal from Trenton northwards to New Brunswick. Two other sections of the canal were piped underground: one in Trenton when the Trenton Freeway (U.S. Route 1) was constructed in 1952, and the other in New Brunswick when the Elmer Boyd Parkway Extension (Route 18) was constructed in 1984.
[edit] State Park
In 1974, most of the canal system was declared a New Jersey state park. It remains one today, and is used for canoeing, kayaking, and fishing. A graded natural-surface trail along the side of the canal, which was the tow path that mules used to tow barges on the canal before steam powered barges, is now used for hiking, jogging, bicycling, and horseback riding. Some 36 miles of the main canal, and all 22 miles (35 km) of the feeder canal, still exist. The park is operated and maintained by the New Jersey Division of Parks and Forestry.
The canal is accessible from many points along its route, with small parking areas providing access at most road crossings. One of the most scenic and popular sections of the D&R Canal state park is the segment along Lake Carnegie in Princeton, New Jersey, which features the canal on one side of the path and the lake on the other side. Another attractive section borders the Colonial Park Arboretum and Gardens in East Millstone.
When the canal was used for transportation, New Jersey's landscape was mostly rural, and its primary business was agriculture. "Now," in the words of Howard Green, research director of the New Jersey Historical Commission, "it is one of the most beloved parks in the state, a sinewy, snake-like greenway through one of the most heavily populated parts of the world. It has gone from being the machine in the garden, to being garden in the machine."
[edit] Associated rivers
- Delaware River - Feeds the Delaware and Raritan Canal via a feeder canal that approaches from the north along the east bank of the Delaware River, starting at Bulls Island, to the southern terminus of the D&R Canal near Trenton.
- Millstone River - Parallels the Delaware and Raritan Canal from Princeton north to Manville. A flood control study is currently being conducted for the Millstone River basin by two government organizations, which may affect the Delaware and Raritan Canal in the future.
- Raritan River - Parallels the Delaware and Raritan Canal from Manville north and east to New Brunswick. The northern terminus of the Delaware and Raritan Canal is in New Brunswick.
[edit] National Register of Historic Places
The Delaware and Raritan Canal was added to the National Register of Historic Places in 1973. It is District #73001105.[1] The many historic canal houses where the bridgetenders lived (such as the Blackwells Mills Canal House and the Port Mercer Canal House) are also on the Register.
