Advanced Bridges

Preferred alternative

The I-94 Modernization Project is rebuilding bridges that are in the poorest condition in a manner that will accommodate the future freeway design. The new bridges are part of the I-94 Modernization Project in Detroit that involves rebuilding 7 miles of freeway and replacing 67 bridges between Conner Road and I-96.

    Second Ave Bridge

    MDOT Receives $1M Innovation Grant for Second Ave Bridge Project In Detroit.

    Built: 1954

    Demolished: Jan. 17 - Jan. 20, 2020

    Features:

    • The new Second Ave bridge will accommodate pedestrians, bicycles and motor vehicles, and feature a variety of aesthetic treatments, including approach landscaping and LED architectural lighting.
    • It will be the first network tied arch bridge in the state of Michigan. "Network" refers to the cables that are crossed from the arch at the top of the bridge to the concrete tie girder that runs along both sides of the bottom of the bridge.
    • At 245 feet long and 96 feet wide, the new structure will be almost the size of a football field, making it substantially larger than the current structure.
    • The skeleton of the new bridge will be constructed off site at the Wayne State University Palmer parking lot (Lot 22) located off West Palmer Avenue between Third and Second Ave. At the same time, on-site construction of the new bridge foundation and abutment wall will be taking place. Allowing both operations to occur simultaneously will save time and help minimize traffic impacts on I-94.

    Offsite Construction: Anticipated to be complete in Spring 2021.

    SPMTs: The 1100-ton bridge skeleton will be rolled across Lot 22 to Second Avenue into its final position over I-94 using Self-Propelled Mobile Transports (SPMTs). SPMTs are multi-axle rolling platforms that can move the heaviest loads. They can be operated mechanically or remotely.

    Open to Traffic: Fall 2021.
