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.

CDOT has made a number of commitments to the local community as part of the Central 70 Project. These cover a range of issues from mitigating the impacts of construction noise and dust to contributing funding to affordable housing and fresh food access. Find out more at the fact sheet below.
