About the Project

Corridor Overview

The Colorado Department of Transportation (CDOT) and the Federal Highway Administration (FHWA), in conjunction with the City of Commerce City and Adams County, are initiating the I-270 Corridor Improvements project to implement transportation solutions that modernize the I-270 corridor to accommodate transportation demands. The 7-mile-long I-270 corridor serves as an inner beltway for the Denver region, providing a direct connection between I-25 and I-70. It is a corridor of commerce, where the region’s key industry clusters of energy, advanced manufacturing, and logistics companies reside.
