Route 64 is a state highway in the U.S. state of New Jersey. It is a state-maintained bridge over Amtrak's Northeast Corridor line in West Windsor. Route 64 begins at an intersection with County Route 571 in West Windsor. It heads along the bridge to an intersection with County Route 615, where Route 64 ends. County Route 571, which is concurrent with Route 64, continues to Hightstown.
Route 64 was designated originally as an alignment of Route 31A, a spur off of State Highway Route 31 (currently U.S. Route 206) from Princeton eastward to Hightstown, where it met State Highway Route 33. The state planned on turning the alignment into a full-fledged expressway for several decades, including constructing the alignment that Route 64 currently uses in 1939. The route was amended in 1941, and was renumbered from Route 31A to Route 64 in the 1953 renumbering. Route 64 was proposed to become part of the Princeton–Hightstown Bypass (later designated Route 92), but completion never occurred. Currently, the route remains the bridge over the Northeast Corridor. However, it is not currently planned that Route 64 will receive an extension of sorts from the proposed Penns Neck Bypass to U.S. Route 1, a proposed realignment of County Route 571.

Route 64 begins at an intersection with County Route 571 and County Route 615 in the community of West Windsor. From this point, County Route 571 continues along the right-of-way towards U.S. Route 130. The route heads north and crosses over Amtrak's Northeast Corridor railroad line before it passes to the north of a local bus depot. Route 64 continues westward for a short distance, crossing through a local woodland and behind several local homes. The route makes a gradual curve to the west off the railroad bridge and passes behind a couple of homes before heading to the south slightly at an intersection. Route 64 reaches its northern terminus and County Route 571 makes a right turn to head northwest toward U.S. Route 1 and Princeton.
