Featured Presentation: Rhode Island DOT Replaces Bridges Over Extended Weekends Using PBES and SPMTs (35 Minutes)

Description:  In September 2016 the Rhode Island Department of Transportation used prefabricated bridge elements and systems (PBES) and self-propelled modular transporters (SPMTs) to replace two substandard bridges in East Providence over two extended weekends. Using ABC resulted in an 83-hour closure for the East Shore Expressway Bridge and, two weekends later, a 65-hour closure for the McCormick Quarry Bridge, resulting in completion of construction a year earlier than would have been possible with conventional construction. Precast elements included approach slabs, abutment caps, wingwalls, railing, and footings connected with grouted splice sleeves. The single-span superstructures were constructed in a nearby staging area and installed using SPMTs. This presentation includes design and construction details and lessons learned.
