Missouri Department of Transportation’s Buck O’ Neil Bridge Design-Build Project

The John Jordan “Buck” O’Neil Memorial Bridge project was driven by the need to replace aging infrastructure and improve traffic flow between downtown Kansas City and northern communities. Originally built in 1956 and rehabilitated in 2018, the bridge had reached the end of its useful life and could no longer meet modern transportation demands. The $220 million project—including a $25 million federal BUILD grant—tackled multiple challenges: deteriorating bridge conditions, outdated street connections, inadequate pedestrian and bike access, and misaligned commuter and local traffic patterns. It aims to improve regional mobility while supporting all modes of transportation.

In the short term, improved traffic control and strategic detours maintained access to key locations like the airport and fire department. The project coordinated effectively with the city to accommodate major events such as the Big 12 Tournament, NFL Draft, and Super Bowl parade. Long-term benefits include enhanced infrastructure for local commuters, ADA-compliant pedestrian improvements, and a shared-use path across the river with lighting and murals that celebrate local history—boosting the city’s accessibility and character. The project benefited from additional opportunities under the Infrastructure Investment and Jobs Act (IIJA). As construction progressed, the expanded scope included rehabilitation of another major Minnesota DOT bridge, supported by IIJA funding.
