Following this, US 611 was rerouted to cross the river twice in order to use the freeway through the Delaware Water Gap, and US 46 was moved to former Route 94 (pre-1953 Route 8) to end at the Columbia, New Jersey side of the Portland-Columbia Toll Bridge. The former approaches to the Darlington's Bridge, which itself was dismantled by the Delaware River Joint Toll Bridge Commission in 1954, became Route 163 in New Jersey and State Route 1039 in Pennsylvania. The US 611 freeway was designated I-80 by 1960, and US 611 was moved back to its old all-Pennsylvania alignment by 1972, leaving US 46 to end at I-80 and Route 94.
