Here, US 1 becomes a four-lane divided surface road with jughandles called the Herbert Highway that is lined with suburban businesses. Continuing northeast, the first intersection along this road is with the eastern terminus of CR 546 (Franklin Corner Road). After this intersection, the road crosses the Delaware & Raritan Canal again prior to a modified cloverleaf interchange with I-295. Past this point, US 1 widens to six lanes as it has an interchange providing access to the Quaker Bridge Mall to the east of the route. A short distance later, there is a cloverleaf interchange with CR 533 (Quakerbridge Road). Upon crossing CR 533, the road enters West Windsor Township. After an interchange with Meadow Road, US 1 continues past corporate parks prior to an interchange with Alexander Road. Following this interchange, the road passes under NJ Transit's Princeton Branch and comes to CR 571 (also signed as CR 526) at the modified Penns Neck Circle, which US 1 runs straight through. Past this intersection, the road passes near farmland.
