Project Overview & Schedule

The Pennsylvania Turnpike Commission (PA Turnpike) plans to reconstruct and widen the Northeast Extension (I-476) from Milepost A53 to A57. The project corridor traverses Lower Macungie Township, passing through Upper Macungie Township, and ending in South Whitehall Township in Lehigh County.

The existing four-lane highway is 72 feet wide and will be widened and reconstructed to 122 feet wide. This new roadway will accommodate three 12-foot travel lanes in each direction, a 26-foot median, and 12-foot outside shoulders (see rendering below). The Design Team is currently developing design plans and coordinating studies in support of the environmental permitting process. The date for mainline construction will be set after the design plans advance.

As part of this multi-phase project, construction is advancing on five overhead bridges. The Tilghman Street Bridge (S.R. 1002) and Lower Macungie Road Bridge Replacement (S.R. 2012) are currently under construction. These bridges must be lengthened to accommodate the wider turnpike roadway before the reconstruction and widening of the mainline can begin. The schedule for the overhead bridge replacements is shown below. More details are available on the Design & Construction page.

The PA Turnpike is coordinating closely with PennDOT and local municipalities as final design and construction progress. The goal is not to disrupt traffic, if possible. Frequently visit our website to stay current on the progress made and the impacts this work may have on your travel on the Turnpike. Sign up for email updates on the news page.

Please contact us if you have questions or concerns. Drive safely.
