At this point, the Trenton Freeway turns onto a depressed alignment, with Conrail Shared Assets Operations' Enterprise Industrial Track closely parallel to the east, and comes to an interchange with Perry Street. The route turns northeast directly over the Delaware and Raritan Canal, which still flows underneath, and has an exit for Olden Avenue. The freeway has a northbound ramp for Mulberry Street before the parallel railroad tracks curve east away from the road and there is a northbound exit and southbound entrance from the median that provides access to US 1 Business and US 206. Past this interchange, US 1 continues into Lawrence Township, where the surroundings become more wooded as the freeway has an exit for Whitehead Road. Along this stretch, the freeway closely parallels the canal, which emerges from under the freeway just north of Mulberry Street. The Trenton Freeway ends at the point US 1 Business merges back into US 1.
