Interstate 295 (Delaware–Pennsylvania)

Interstate 295 (I-295) in Delaware, New Jersey, and Pennsylvania is an auxiliary Interstate Highway, designated as a bypass around Philadelphia, Pennsylvania, and a partial beltway of Trenton, New Jersey.

The route begins at a junction with I-95 south of Wilmington, Delaware, and runs to an interchange with I-95 in Bristol Township, Pennsylvania. The highway heads east from I-95 and crosses the Delaware River into New Jersey on the Delaware Memorial Bridge concurrent with U.S. Route 40 (US 40). Upon entering New Jersey, the New Jersey Turnpike and US 40 split away and I-295 runs parallel to the turnpike for most of its course in the state. After a concurrency with US 130 in Gloucester County, I-295 has an interchange with I-76 and Route 42 in Camden County. The freeway continues northeast toward Trenton, where it intersects I-195 and Route 29 before bypassing the city to the east, north, and west, crossing the Delaware River on the Scudder Falls Bridge into Pennsylvania. In Pennsylvania, I-295 is signed as an east–west road and heads south to its other terminus at I-95. I-295 is one of two auxiliary Interstates in the US to enter three states, the other being the I-275 beltway around Cincinnati, which enters Ohio, Indiana, and Kentucky.

Three portions of I-295 predate the Interstate Highway System: the Delaware Memorial Bridge and its approach, built in 1951; a section in Salem County, built in 1953; and the part concurrent with US 130, built in two sections that opened in 1948 and 1954. The route was designated on these sections in New Jersey in 1958 and in Delaware in 1959. The portion of I-295 connecting to I-95 in Delaware opened in 1963 while most of the route in New Jersey was finished by the 1980s. The part of I-295 near the interchange with I-195 and Route 29 was finished in 1994. I-295 previously ended in New Jersey at US 1 in Lawrence Township, becoming I-95 heading south into Philadelphia. By July 2018, I-295 was extended along the former I-95 in New Jersey and Bucks County, Pennsylvania, to end at I-95 at the Pennsylvania Turnpike, with no access between I-295 and the latter road. Improvements continue to be made to the highway, including reconstruction of interchanges and replacement of bridges.
