Central 70

A new name for a project that is Central to Communities, Connections, Commerce and Colorado

The Project

Central 70, between I-25 and Chambers Road, is one of Colorado's economic backbones: home to 1,200 businesses, providing the regional connection to Denver International Airport and carrying upwards of 200,000 vehicles per day. It's time to bring this aging highway into the 21st century and rejoin communities along the way.

 The Central 70 project proposes to reconstruct a 10-mile stretch of I-70 East, add one new Express Lane in each direction, remove the aging 50-year old viaduct, lower the interstate between Brighton and Colorado boulevards, and place a four-acre cover over a portion of the lowered interstate.

The Cover

An active and vibrant public space is planned for Colorado's first highway cover. This four-acre space is being designed in partnership with local residents, the City of Denver and Swansea Elementary School.

Preparing for Construction

CDOT plans to hire one development team to be responsible for design, construction, operations and maintenance of the Central 70 project. There are currently four teams of finalists who have been selected to respond to a request for proposals (RFP) for the project.
