Interstate 195 (I-195) is an auxiliary route of the Interstate Highway System located in the US state of New Jersey. Its western end is at I-295 and Route 29 just south of Trenton in Hamilton Township, Mercer County, while its eastern end is at the Garden State Parkway, Route 34, and Route 138 in Wall Township, Monmouth County. I-195 is in length. The route is mostly a four-lane highway that mainly runs through agrarian and wooded areas in Central Jersey. It has an interchange with the New Jersey Turnpike (I-95) in Robbinsville Township and serves as a main access road to New Jersey's state capital of Trenton, the Horse Park of New Jersey, the Six Flags Great Adventure amusement park, and the Jersey Shore. I-195 is occasionally referred to as the Central Jersey Expressway. On April 6, 1988, President Ronald Reagan signed H.R. 4263 naming I-195 in New Jersey the James J. Howard Interstate Highway, in honor of the late James J. Howard. The current I-195 was initially planned as a toll road called the Trenton–Asbury Park Expressway in the 1950s. In the 1960s, it became two proposed freeways Route 37 and Route 38 that were to cross the central part of the state. A compromise was reached for a single freeway between Trenton and Belmar which would get Interstate Highway funding as I-195. It was built in several stages during the 1970s and 1980s. There once existed a plan to extend the I-195 designation west to the interchange between the Pennsylvania Turnpike (I-276) and I-95 in Bristol Township, Pennsylvania, but it was decided to extend the I-295 designation west and south, along existing I-95 instead. Route description I-195's western terminus is at a modified cloverleaf interchange with I-295 in Hamilton Township, Mercer County, located southeast of the city of Trenton. From this end, the freeway continues north into Trenton as Route 29. I-195 serves as the southern continuation of Route 29, continuing east from I-295 as a six-lane expressway, passing between suburban neighborhoods to the north and Crosswicks Creek to the south. After the exit for U.S. Route 206 (US 206), the highway narrows to four lanes and turns northeast as it interchanges with County Route 524 (CR 524) and CR 620. Following this, I-195 passes near more neighborhoods and runs to the northwest of Gropp Lake before turning more to the east. The route has a cloverleaf interchange
