Exit 53 is for Pennsylvania Avenue (US 6/US 209). Due to construction, all traffic is forced into what are normally the eastbound lanes, with one lane for each direction. There is a temporary ramp crossing over to the westbound lanes to provide access to the exit.

Approaching the state line, there is advance signage for exit 1 in New York, which is for US 6 and NJ 23. The sign is in Pennsylvania, the exit is in New York, and it references a state route in New Jersey. Straight ahead, there is a bridge over the Delaware River to New York.
