Interstate 195 (abbreviated I-195) is an auxiliary route of the Interstate Highway System located in the U.S. state of New Jersey. Its western end is at I-295 and Route 29 just south of Trenton, New Jersey  in Hamilton Township, Mercer County while its eastern end is at the Garden State Parkway, Route 34 and Route 138 in Wall Township. I-195 is in length. The route is mostly a four-lane highway that runs through wooded areas in the center of New Jersey. It has an interchange with the New Jersey Turnpike (I-95) at Exit 7A in Robbinsville Township and serves as a main access road to Six Flags Great Adventure (which is off the CR 537 exit in Jackson Township) 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 Interstate 195 in New Jersey the James J. Howard Interstate Highway, in honor of the late James J. Howard.
