Trenton–Mercer Airport via a cloverleaf interchange. After CR 611, the highway crosses back into Ewing Township and passes to the northwest of the airport. An interchange with CR 579 also serves Trenton–Mercer Airport. The freeway comes to the Route 29 interchange that also has a northbound entrance from Route 175. At this point, maintenance of the road changes from NJDOT to the Delaware River Joint Toll Bridge Commission (DRJTBC), and I-295 widens from six to eight lanes. Immediately after the interchange with Route 29, I-295 then crosses the Delaware River into Pennsylvania on the tolled Scudder Falls Bridge. At the state line, I-295 transitions from a north–south road to an east–west road, with the northbound direction turning into the westbound direction upon crossing into Pennsylvania and the eastbound direction turning into the southbound direction upon crossing into New Jersey. Upon crossing the Delaware River, I-295 becomes the Delaware Expressway (Vietnam Veterans Memorial Highway) and enters Lower Makefield Township in Bucks County, passing over Pennsylvania Route 32 (PA 32) and reaching an electronic toll gantry in the westbound direction. After crossing the Delaware Canal, I-295 reaches an interchange with Taylorsville Road, which provides indirect access to PA 32, to the north of the borough of Yardley, and narrows to six lanes. Here, the Pennsylvania Department of Transportation (PennDOT) takes over maintenance of the road. At this interchange, the route changes cardinal directions, with northbound becoming westbound and eastbound becoming southbound. I-295 continues west-southwest near suburban residential areas and features a westbound rest area and weigh station. The freeway turns to the south and reaches the PA 332 interchange that serves the borough of Newtown to the west, narrowing again to four lanes. I-295 continues south near some farmland before passing near more homes with some commercial development. The freeway comes to a bridge over SEPTA's West Trenton Line and CSX Transportation's Trenton Subdivision before it crosses into Middletown Township and comes to a cloverleaf interchange with the US 1 freeway. Immediately after this interchange, I-295 passes over Norfolk Southern's Morrisville Line and CSX Transportation's Fairless Branch as it curves southwest, heading northwest of commercial development and the Oxford Valley Mall. The freeway makes a curve to the south and becomes parallel to SEPTA's West Trenton Line and CSX Transportation's Trenton Subdivision to the west, passing under PA 213 without an interchange. The railroad tracks split to the west and I-295 reaches
