[Webinar] Central 70 Colorado Cover Top Best Practices and Lessons Learned

February 20, 2023      By Adam Mercer, Marshall Bailey, PE, Assoc. DBIA

Tags: Transportation

The Central 70 Interstate is known to many as Colorado’s economic backbone, carrying upwards of 200,000 vehicles per day. The Central 70 project is the state’s largest public-private partnership (P3) transportation project to date, designed to cut travel time in half by the year 2035 and bring major infrastructure improvements to one of the region’s most critical highway segments.

The project reconstructed a 10-mile stretch adding one new Express Lane going in each direction while removing the aging 57-year-old viaduct. The project also lowered the interstate, providing access to a new 4-acre park over a portion of the lowered interstate. This cover will provide more connection for the community that was originally divided by the interstate. These community spaces will include parks and amphitheaters.
