Interesting Bridge Design Example

The Martin Olav Sabo bridge is a signature cable stayed bridge in Minneapolis, located just north of (and parallel to) Lake Street. The bridge is 2,200 feet long with a main clear span of 220 feet, which crosses both Hiawatha Ave (MN-55) and the Hiawatha light rail line. The bridge was built to carry the Midtown Greenway, a crosstown grade-separated bicycle expressway, across the very busy Hiawatha Ave and light rail lines without a need for the bicycle riders to cross at street level.
 
This fantastic bridge was paid for by a grant from the United States Congress as a result of advocacy by former Congressman Martin Sabo and earmark of $2.9 million in federal funding to the project. After bridge construction, the County gave the bridge to the City of Minneapolis to own and maintain it.
