YP Sponsored Tour: Historic 3rd Avenue Bridge Rehabilitation- Thursday, August 25, 2022

Special thanks to the DBIA-UMR Young Professionals Committee for organizing the tour!  

Project Overview
The 3rd Avenue Bridge spans 1,888 feet across the Mississippi River between downtown Minneapolis and St. Anthony Main to the north. The open spandrel concrete arch bridge was constructed between 1914 and 1917 and is located within the St. Anthony Falls Historic District. Deteriorated original and rehabilitated elements warranted extensive concrete repair and full deck and spandrel replacement in order to extend the bridge service life. Repairs to this bridge present particular challenges because of the bridge’s unique design and the constrained site access created by the Upper St. Anthony Falls Lock and Dam. Construction led by Ames Construction began in 2020 and is expected to be completed in early 2023.   The  MnDOT-led project tour focused on the column, cap beam and deck reconstruction with unique staging sequences as well as historic concrete surface repairs.​
