I-64 Daniel Boone Missouri River Bridge

As the engineer of record for the Daniel Boone Bridge, Burns & McDonnell helped the Missouri Department of Transportation (MoDOT) provide a major new Missouri River crossing maximizes mobility, connects nearby bike paths and minimizes maintenance costs over the next century.

This $111 million design-build project includes design and construction of a new 2,615-foot bridge, repairs to the existing eastbound structure, and demolition of the existing westbound structure. The new bridge accommodates eastbound traffic, and the rehabilitated bridge carries westbound traffic. 

The bridge carries four lanes of eastbound traffic and has a 64-foot clear roadway and a barrier-protected 10-foot wide bike-pedestrian path connecting the Katy Trail and the Monarch Levee Trail. The project was completed without reducing the number of lanes during construction. By working diligently to offer a state-of-the-art design under the client’s fixed budget, Burns & McDonnell was able to apply the savings toward project enhancements, including:
