Abstract:
During bridge construction, a form at the upper, outer edge of a bridge's outer girder, upper flange retains concrete slurry poured on the bridge's deck. The girder is cast with extended upper flanges, and the form is precast integrally with the flange. The improved girder may eliminate the need for a construction worker walkway.
