Boone County: Potential Interstate 70 Exit Ramp Removal

Project Details:

This project could take place when funding becomes available.

The total estimated cost to remove the existing structure and close the off-ramp is $1.2M.

Proposed Work: 
Removal of the Interstate 70 westbound ramp to Business Loop 70, including the bridge (L0928) constructed in 1957 over eastbound I-70 in the City of Columbia between Route B (Paris Road) and the I-70/U.S. Route 63 Connector. 

Traffic Impact:  
The I-70 westbound ramp to I-70 Business Loop will be closed during demolition.  Temporary lane closures will be intermittently needed on I-70 during construction.
