I-94 2nd Avenue Bridge Network Tied Arch

Prize Bridge Award Winner: I-94 2nd Avenue Bridge Network Tied Arch 

The first skewed and unbraced network tied arch bridge in the U.S., the I-94 2nd Avenue Bridge Network Tied Arch features four planes of steel hanger cables crossing from the top of the arch rib to the tie girder, the inclined cables dramatically increase structural stiffness, reduce dead and live load deflections to approximately 10% compared to a vertical hanger system, and increase structural redundancy. 

Now a core piece of Detroit’s $2 billion Interstate 94 corridor reconstruction and downtown revitalization plan, this bridge won NSBA’s 2024 Medium Span National Award and became a finalist for Bridge of the Year!
