PHOENIX – A new technique that basically slides precast bridges into place has greatly reduced delays for the Bellemont community with an Arizona Department of Transportation project replacing spans over Interstate 40 at Transwestern Road west of Flagstaff.
Using this technique, which the contractor proposed, allowed crews to replace the bridges during a nine-day closure of Transwestern Road over I-40 rather than having the six to eight months of restrictions required for a traditional bridge replacement project.
