The southern third of CR 533 serves as a shorter, more direct route between two parts of US 206, connecting the southern portion as it travels north from Bordentown and the northern portion as moves through Princeton and into Somerset County. The U.S. highway turns west down Broad Street at the circle and winds confusingly through the city of Trenton before moving through Lawrence, the county route continues nearly due north through Hamilton and along the Lawrence/West Windsor boundary into Princeton. CR 524 also begins at the circle, following Broad in the other direction toward Yardville and Allentown.
