NORTHEASTERN EXTENSION MILEPOST A38-A44 TOTAL RECONSTRUCTION PROJECT

Description

Phase 1 - Mainline (I-476) - From MP A37.4 (Clump Road) to MP A43.3 (John Fries Highway - SR663) total reconstruction and widening, and Turnpike bridge over Kumry Road (SR 4055) replaced. Construction is anticipated to begin in 2021, or later.

Phase 2 - Mainline (I-476) - From MP A43.3 (John Fries Highway - SR 663) to MP A44.5 total reconstruction and widening. Quakertown Interchange reconstructed, and John Fries Highway bridge over Turnpike replaced. Construction is anticipated to begin in 2024, or later.

Final Design began in 2014 for the total reconstruction and widening of the Pennsylvania Turnpike's Northeastern Extension (I-476) north of Clump Road (milepost A38) to north of Steinsburg Road (milepost A44.5). The existing four-lane highway (74' wide) will be reconstructed to accommodate six 12-foot travel lanes with 12-foot left and right shoulders and 2' median barrier (122' wide). The project will also include the reconstruction of the Quakertown Interchange and the removal and replacement of five mainline bridges. The project corridor traverses Salford Township in Montgomery County and West Rockhill and Milford Townships in Bucks County.

The project also includes the replacement of the following bridges over the Turnpike, prior to the Turnpike widening.

  • Upper Ridge Road Bridge (State Route 4033) — Construction completed – new bridge open to traffic as of 6/30/2021
  • Trumbauersville Road Bridge (State Route 4051) — Construction completed – new bridge open to traffic as of 11/22/2017
  • Steinsburg Road Bridge (State Route 4059) — Construction completed – new bridge open to traffic as of 11/22/2017

The Project's Design Team continues to develop design plans in support of the environmental permitting process. An Open House Plans Display was held on December 3, 2014 to introduce the Preliminary Design Plans to the Public. The materials from the Open House can be viewed on the Public Involvement page.

Typical

At project completion, the section will consist of 6 travel lanes (3 westbound and 3 eastbound), with a 26-foot median, and 12-foot outside shoulders.
