ABOUT THE PROJECT

MoDOT has replaced all of the bridges within the I-435 and I-70 interchange. In addition to the new bridges, crews enhanced the safety of the interchange overall with a new design. This new configuration is a partial turbine and provided an opportunity to make additional safety improvements in a cost-effective manner. Improvements included full bridge replacements, removal of the less traditional left exits, improvements to loop ramp configuration, and congestion relief. 



This project was identified as one of the possible improvements to ease congestion and crashes often caused by merging and weaving in the I-70 Environmental Impact Study.

 

Emery Sapp and Sons was the main contractor on this project. Construction began in March 2019 and was scheduled to be completed by December 2020, but finished in early October 2020.

This is a $47 million project and is fully funded by MoDOT.
