New Jersey Route 75: Route 75 was a proposed freeway in the U.S. State of New Jersey in the Newark area in 1960s and 1970s.  It was designed to connect the existing Route 21 freeway north of Newark with Interstate 78, U.S. Route 1-9, and Newark Airport.  The state of New Jersey applied for interstate status for the route in 1970, but construction of the road remained stalled in courts throughout the 1970s.  In 1973, the state of New Jersey and the Federal Highway Administration shelved plans for the route, and in 1997, the state of New Jersey officially removed the route from its route logs.  Despite its removal, vestiges of Route 75 still remain.  The first example is Exit 13 on Interstate 280 eastbound in Newark.  The exit is an enormous three lane ramp, while through traffic on I-280 has only two lanes.  The ramp comes to a stop at a traffic light on First Street, just south of Orange Street.  Also, at Exit 56 off Interstate 78, large flyover ramps meant for a freeway diverge from the roadway, but terminate at city streets.
