State Route 30 A25 Rapid Bridge Replacement Timelapse

Work was completed in May 2016 to replace the Route 30 bridge over Bessemer Avenue in East Pittsburgh in Allegheny County. The single-span structure was replaced using accelerated bridge construction methods. It was demolished and replaced in just 57 hours using precast modules. Around 20 workers on 12-hour shifts cleared much of the old structure and pieced together the new one. It replaces a 1930 bridge that had become structurally deficient. The stretch of Route 30 carries about 22,000 vehicles a day.
