Turnpike Milepost A31-A38 Project

Project Overview

Construction begins in early 2018 on the Total Reconstruction and Widening of the Northeastern Extension of the Pennsylvania Turnpike (I-476) from north of the Lansdale Interchange to north of Clump Road, between Mileposts A31 and A38. The seven-mile project corridor traverses Lower Salford, Franconia and Salford Townships in Montgomery County.

Project Area Map

This section of the Northeastern Extension will be completely reconstructed from the ground up and widened from two lanes-to-three lanes in each direction with 12-foot right and left shoulders. The new and existing lanes will be composed of an asphalt pavement base topped by an asphalt riding surface.


The project will be built in two major Construction Stages (Stages 2&3), with a brief initial stage (Stage 1) to prepare the work zone.

The northbound and southbound Extension is expected to be open to three (3) lanes in each direction by late fall 2020. The entire project will finish by early summer 2021.

A companion project to widen and reconstruct the Extension between Milepost A38 and A44 and reconstruct the Quakertown Interchange remains in the Design stage of project development, with mainline construction tentatively scheduled to begin in 2021.

The Turnpike also will install a number of Intelligent Transportation Systems (ITS) components as part of this project, including electronic message signs (Dynamic Message Signs) that are used to alert motorists of incidents, lane closures and other important traveler information.
