Turnpike Milepost A31-A38 Project

Construction Update

Fall/Winter 2019/2020

New Outside Lanes Built, Reconstruction of Center Area Underway

Two lanes of northbound and southbound traffic were shifted to the outside onto the new third lane and shoulders on November 17 and Stage 3 construction is now underway on the middle section of the Northeastern Extension (Interstate 476) between Mileposts 31 and 38.

Construction continuing through the winter of 2019 / 2020 will remove the existing Turnpike bridge structures over Schoolhouse Road, Creamery Road, Dietz Mill Road and the East Branch of the Perkiomen Creek. Once removed, crews will begin the process of reconstructing the footings, abutment walls and piers at each bridge structure.

At the same time, the concrete pavement of the existing four lanes will be rubblized and used as a sub-base for the new pavement that will be placed later during Stage 3 construction. This final stage also includes placement of a new concrete median barrier.

During Stage 3 construction, trucks and buses are restricted to the left lane only in both the northbound and southbound direction through the project limits. Occasional short-term, off-peak lane restrictions also may occur during this final stage of the project.

In addition to adding a third lane in each direction and building the widened areas of the four overpasses, completed Stage 2 construction included installation of new stormwater drainage components and retention basins and erection of sound barrier walls at four locations along the seven-mile work area.

The entire project is expected to be completed in late 2020.
