Project Overview & Schedule
The Pennsylvania Turnpike Commission (PA Turnpike) plans to reconstruct and widen the Northeast Extension (I-476) from Milepost A48–A53. The project corridor traverses Lower and Upper Milford Townships, Borough of Emmaus, and Lower Macungie 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. Below is the anticipated schedule.
As part of this multi-phase project, the PA Turnpike advanced two overhead bridges at Vera Cruz and Indian Creek Roads. The Vera Cruz bridge was completed in 2023. The Indian Creek Road bridge was completed in late 2024. See the Design & Construction page for more details.
The PA Turnpike will continue to coordinate closely with PennDOT and local municipalities when the mainline final design and construction phases progress. The PA Turnpike's goal is to minimize disruption to local traffic
