Travel directions

The highway begins at Interstate 287, the metropolitan area’s western bypass, and heads southeast. There are 2×2 lanes available. One passes through wooded suburbs such as Madison and Chatham. A little further on, the road widens to 2×3 lanes, and the highway ends at Interstate 78 toward Newark and New York.


Plans for a highway on the current route date from 1950, and in 1952 a highway was assigned to bypass some suburbs on the route. The route was approved in 1960 and construction began in 1967. In 1972, the section between Interstate 78 and Florham Park was completed. It wasn’t until 1988 that construction continued to build the last 2 miles to Interstate 287, which was completed in 1992.

State Route 28 or SR-28 is a state route in the U.S. state of New Jersey. The road forms an east-west route through suburban areas between Bridgewater and Elizabeth. The road is 43 kilometers long.

Travel directions

State Route 28 in Bridgewater.

State Route 28 is largely a 2- or 4-lane urban arterial through a string of suburbs southwest of Newark, from US 22 in Bridgewater to US 1 in Elizabeth. Most of the road runs parallel to US 22 for a short distance. The entire route leads through built-up areas and has numerous intersections. However, the road has not been developed to a high standard and forms the main street of many places on the route, so that a lot of retail is located on the road. There are connections to Interstate 287 and Garden State Parkway.


The road was originally numbered Route 9 from 1917, which ran from Philipsburg to Elizabeth. When the US Highways system was introduced in 1926, US 22 took over the entire route, resulting in double numbering, but in 1927 Route 9 became Route 28, so US 22 and Route 28 were double-numbered. The road then continued on to the Goethals Bridge to Staten Island. US 22 was moved in 1941 to a parallel route that was more convenient for through traffic, because State Route 28 passes through every town. Since 1953 the route ends in Elizabeth and no longer at the Goethals Bridge.

State Route 29 or SR-29 is a state route in the U.S. state of New Jersey. The road forms a north-south connection in the center of the state, along the Delaware River, from Hamilton through Trenton to Frenchtown. The portion through the capital Trenton is a highway, the rest of the route is a quiet scenic route through the valley of the Delaware River. The route is 56 kilometers long.

Travel directions

State Route 29 to the south of Trenton.

The highway begins on the southeast side of Trenton, at Hamilton Township at the interchange with Interstate 195, which leads to Belmar, and Interstate 295, which forms Philadelphia ‘s eastern bypass. The motorway will initially have 4+3 lanes and narrow within the boundaries of Trenton to 2×2 lanes. Here, the highway runs directly over the bank of the Delaware River. A park has been built on the highway in Trenton. This is followed by two traffic lights, after which the road again becomes a motorway with 2×3 lanes. One crosses the US 1. Pretty soon the road narrows back to 2×2 lanes, continuing northwest along the Delaware River. After a few kilometers the road loses its highway status again and there are a number of at-grade intersections.

On the north side of Trenton, one crosses Interstate 295. After this, the road is definitively a secondary road with one lane in each direction. The road runs through densely wooded area that starts to get hillier. At Lambertville you cross the US 202. The road is now a tourist route through the Delaware River valley. In Frenchtown the road ends on several other local roads.


In 1932, a parkway system was proposed on the model of Robert Moses in New York City. One of these plans was to be a route across the east bank of the Delaware River through Trenton. However, the plan was not implemented. In the 1950s, plans resurfaced for an east-west route along the Delaware through Trenton. In 1954, the first section from South Warren Street in Trenton to I-95 was under construction, which was completed in 1957. This was not entirely a highway, there were a limited number of intersections.

The eastern part took a lot longer. Construction began in 1990 on the section between downtown Trenton and I-195 in Hamilton, which was completed over 3 kilometers in 1995. In the 1960s there were already plans to connect both parts, but this was never built, so that there are a number of level crossings near the center. In 1997, construction began on a missing link between downtown and the existing NJ-29 in South Trenton. A part is built in a covered tunnel. This plan was to be completed in 2001, but was delayed due to technical problems. The tunnel barge opened on March 2, 2002. At the same time, Trenton’s waterfront was greatly improved with a new park.

The route first ran from Trenton to Newark from 1927, but was renumbered to its current routing in 1953 as Route 29A, which later became Route 29.

Traffic intensities

State Route 29 is not a busy highway with around 45,000 vehicles in Trenton. North of Lambertville, this drops to 2,000 vehicles per day.
