After the US 1 cloverleaf interchange, the road name briefly changes to Province Line Road and intersects an access road to Mercer Mall. At the next traffic light, it intersects the access to the Nassau Park shopping center and Province Line Road, unsigned CR 569. North of this intersection, CR 533 becomes unsigned and is known as Quaker Road. After crossing the Delaware and Raritan Canal at Port Mercer, Quaker Road becomes under the jurisdiction of Princeton, turns off the Keith line into the borough, and crosses Stony Brook on Quaker Bridge. Paralleling Stony Brook and adjacent to farmland, CR 533 intersects Princeton Pike, also known as CR 583, before winding its way through a small residential area, narrows such that it becomes traversable for northbound traffic only, and reaches its intersection with US 206.
