C-470 Express Lanes

The C-470 Environmental Assessment Document was signed by the Federal Highway Administration and the Colorado Department of Transportation in February 2006. This project has been on hold since 2006. In February of 2013, the C-470 Coalition obtained consensus on Express Lanes as the preferred C-470 funding alternative in partnership with CDOT. In a continued partnership with the C-470 Coalition, CDOT is preparing a Revised Environmental Assessment (EA) and will enter into design-build procurement in the Spring of 2014. The Express Lanes alternative being analyzed in the Revised EA differs from the 2006 EA. The current alternative has different access designs and locations, no longer includes a barrier separation and includes auxiliary lanes in select locations. All information related to the design-build project will be made available on this site.
