Pittsburgh bridge demolished in dramatic explosion

July 16, 2026

A bridge in Pittsburgh, Pennsylvania was destroyed through controlled explosive demolition to make way for its replacement. The Pennsylvania Department of Transportation has already constructed a new Commercial Street Bridge that will be moved into its final position using a lateral sliding technique. The new structure will be transported at a speed of 19 feet per hour in what officials describe as the largest lateral slide bridge project ever undertaken in Pennsylvania.

Why it matters

This project represents a significant infrastructure improvement for Pittsburgh using an innovative lateral slide construction method. The approach allows for a faster replacement process since the new bridge was pre-built and can be moved into position, reducing the time the crossing would otherwise be unavailable. As the largest lateral slide project in Pennsylvania's history, it demonstrates advanced engineering techniques for major infrastructure replacement.
