The 174-foot, 950-ton section of the bridge was built adjacent to Southwest
Eight Street using Accelerated Bridge Construction (ABC) methods, which are
being advanced at FIU’s Accelerated Bridge Construction University
Transportation Center (ABC-UTC). This method of construction reduces
potential risks to workers, commuters and pedestrians and minimizes traffic
interruptions. The main span of the FIU-Sweetwater UniversityCity Bridge was
installed in a few hours with limited disruption to traffic over this weekend.
