The Pennsylvania Turnpike - Lehigh River Pohopoco Creek Bridge Replace Project

The Pennsylvania Turnpike Construction and Expansion | Lehigh River and Pohopoco Creek Bridge Replacements Project

Welcome to the website for the Pennsylvania Turnpike’s Lehigh River/Pohopoco Creek bridge replacement projects.

As part of our continuing investment in America's transportation infrastructure, the Pennsylvania Turnpike Commission is replacing two bridges on the Northeastern Extension (I-476) in Carbon County with four new spans. The structures are located approximately two miles north of the Lehigh Tunnel between mile markers 73.52 and 75.29.

We'll use this portal to provide you with transparency into the progress of construction and any traffic impacts that you may encounter on the Turnpike or the local road system in the project area.

See an overhead rendering of the new bridges and construction progress photos here.

Tune to Highway Advisory Radio for traffic conditions from every interchange.

Lehigh Abutment
Work is nearing completion on the northern abutments for the new Lehigh River Bridges adjacent to Route 248. The polyethylene covering is used to insulate the newly-poured concrete so that it cures properly during cold weather.
