The 10th Avenue Bridge (Bridge 2796) is a critical transportation element of the Minneapolis riverfront area. Currently, it carries approximately 10,000 vehicles and hundreds of pedestrians over the Mississippi River each day.
The bridge is listed on the National Register of Historic Places under Criterion “A” (Community Development – Transportation) and Criterion “C” (Engineering Design). Built in 1929, it has admirably carried traffic over the Mississippi River for nearly 90 years. However, leaking expansion joints and leaking drainage elements have led to deterioration of concrete components. This deterioration is a mixture of freeze thaw damage and corrosion based damage.
The City of Minneapolis, along with the SEH consultant team, are working together to design a rehabilitation project for the bridge that meets several goals, including:
Coordinating with multiple stakeholders and agencies
Staying within the project budget
Construction that results in an attractive bridge with durable details
Does not compromise the historic integrity of the bridge
The design work for the rehabilitation project will be completed by the spring of 2019. Construction will begin in the fall of 2019, and will continue into late fall 2020. There will be traffic impacts and detours during construction.
