State Highways of New Jersey

The highway runs concurrently with several other 500-series routes, including SR 526 for a mile and a half in Monmouth and Ocean counties. Mercer County signs SR 526 along with SR 571 for a distance in West Windsor and Princeton, but NJDOT says that SR 526 starts at the split from SR 571 in West Windsor rather than running with SR 571 for its last 4¼ miles.

A NJDOT-built crossing of the Pennsylvania Railroad mainline in West Windsor is designated NJ 64.

While the NJDOT inventory of the highway designates it as a north-south road, both Ocean and Mercer counties sign it as running east-west. Monmouth County alone goes with NJDOT’s north-south designation.
