Summary
The Missouri Highways and Transportation Commission selected the team of Walsh Construction Co. of Chicago and J.S. Alberici Construction Co.

KEG was the lead designer on all roadway improvements associated with the bridge construction.
Project
The project’s primary purpose was to replace a deficient bridge with a new Missouri River bridge connecting St. Charles and St. Louis Counties. The $125 million project also included removal of the deteriorated westbound span built in 1935; improvements to the existing eastbound span, which opened in 1989; a new Chesterfield Airport Road interchange, including connecting the North Outer Road to the westbound Interstate 64 on-ramp; and building a continuous westbound fourth lane from the Chesterfield Airport Road entrance ramp to the Highway 94 exit ramp. These improvements provide eight lanes, four in each direction, for 3 miles between Chesterfield Airport Road and Highway 94. The project also added a shared-use path on the new span connecting the Katy Trail in St. Charles County to the Monarch Levee Trail in St. Louis County.

KEG staff designed improvements to I-64, Ramps 1 and 2 at I-64, the Spirit of St. Louis Boulevard, and the North Outer Road to Ramp 2. Highway design included typical sections and plans, profiles, and cross-sections. Horizontal and vertical geometry, super elevation, and guardrail/barrier design were also included. KEG designed and coordinated signing and striping plans and the erosion and sediment control plans for the project.
The entire project team including MoDOT staff, contractors, and design consultants worked together in a project office located just outside the project limits to make this a successful project for all.
Construction of the new eastbound span of the Daniel Boone Bridge is now complete and open to traffic.
