Second Avenue bridge replacement


Routine inspections of the Second and Third Avenue bridges over route I-94 found major structural problems in 2017 and 2019.

Each bridge was immediately closed, disrupting traffic between campus and neighborhoods to the north. These closures also blocked the most direct routes between the Biological Sciences Building and Tech Town, iBio and Campus Safety. The Michigan Department of Transportation (MDOT) is now replacing the 66-year-old Second Avenue bridge with the first network-tied arch bridge in Michigan.

It will feature a central arch with crossed hangers supporting the roadbed, a design with benefits in cost, strength and stability. The new bridge does not require a central pier, a feature that is important for a planned modernization of I 94 over the next 10 years. Construction of the arch, now taking place in a parking lot near the WSU Law School, is well underway. 

When completed the arch will be rolled into place over I 94 – a must-watch event!
