The Central Jersey Expressway system plans in the late 1950s outlined a route for New Jersey Route 37, the Trenton-Asbury Park Expressway, running east from Trenton to the Garden State Parkway near Toms River. Interstate funding for the Central Jersey Expressway (Route 37), estimated at $60 million, was proposed in 1967 in exchange for dropping funds for a seven mile long portion of Interstate 278, which was estimated to cost nearly $100 million. This proposal did not move forward until 1968, when the Bureau of Public Roads approved an additional 1,500 miles to the national Interstate system, which allowed for the 34.2 mile expansion of I-195.1
Construction began on Interstate 195 in October 1968 in western Upper Freehold Township. The majority of the route was completed by 1981. The western most 1.8 miles opened in two stages between 1987 and 1990.1 Work on the Trenton Complex project involving I-295 south from I-195 to Bordentown and Route 29 north from I-195 into Trenton, commenced in 1990. Prior to its completion in December 1994, I-195 acted as the default route for I-295 between Trenton Belt Line and U.S. 206 south to U.S. 130 at Bordentown.
Plans for the interchange between the Pennsylvania Turnpike and Interstate 95 at Bristol involved the relocation of I-95 from the Trenton Belt Line onto the toll road east to the New Jersey Turnpike. A petition to the American Association of State Highway and Transportation Officials (AASHTO) in 2007 gave preliminary approval to renumber the former I-95 between Bristol and Lawrence Township, New Jersey and I-295 from White Horse and U.S. 1, as an extension of Interstate 195. This changed again in 2014, when a proposal emerged to instead renumber this as Interstate 395. By 2015, the original plan to extend I-295 west to Bucks County, Pennsylvania over the old route for I-95 was approved by AASHTO. Flyovers connecting I-95 with the Pennsylvania Turnpike at Levittown, Pennsylvania opened to traffic on September 23, 2018, finalizing the extension of I-295.
