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.

Blasting Rock
A cloud of dust rises immediately after a blast is set off to loosen rock on the south side of the Lehigh River. The outcropping is being removed to make way for the approach to the new bridges.
