­­Description:  As the main western gateway into Nashville, the Broadway Viaduct Bridge is a crucial arterial for the city, carrying 26,000 vehicles and 7,000 pedestrians daily, as well as critical communication infrastructure for downtown. Replacing the old bridge was an incredibly complex endeavor that included working closely with many stakeholders, such as the Nashville Department of Transportation, CSX Railroad, property owners and developers. The webinar will focus on how the project was delivered under the innovative construction manager/general contractor (CM/GC) delivery method and also how the bridge was replaced by using ABC techniques that resulted in the complete replacement of the bridge superstructure during a mere 8-week full closure of the bridge.  The presentation will include best practices and lessons learned.  This project was accomplished with an 8 week full closure and was reopened to traffic in September of 2023.
