Route 248/US 65 Diverging Diamond Interchange

diverging diamond

Benesch completed a conceptual study and design to reconfigure an interchange to accommodate the increasing amount of traffic. Route 248 was a three-lane bridge over US 65, and the bridge could not be widened to more than one girder without resulting in significant structural issues and costs. Due to these constraints and identified traffic patterns, the determined design solution used a Diverging Diamond Interchange (DDI).

The existing interchange configuration was a traditional diamond. Existing ramps were left in place and widened to accommodate the new design. The Missouri Department of Transportation system required sidewalks, which limited the bridge to three through lanes of traffic. The sidewalks and accompanying barriers were provided in the median across the bridge. This DDI was one of the first designed in the State of Missouri.
