I-70 FLOYD HILL PROJECTA Little Planning. More Room for Adventure.
What’s Taking ShapeThe Floyd Hill project is designed to make this stretch of I-70 safer and travel more reliable. Work includes rebuilding bridges, easing sharp curves, adding a westbound tolled Express Lane, and improving connections along the corridor. The project also includes Clear Creek Greenway improvements and work to support wildlife passage and stream health. Full completion is currently expected in 2028.
Walking or biking nearby? The Clear Creek Greenway between US 6 and Hidden Valley is closed for construction, with the closure expected to continue through 2029. Check the closure map before planning your route.

Know before you go.
Lane closures, shifting traffic patterns, reduced speeds, and occasional overnight detours can affect travel through Floyd Hill. Leave extra time, especially if you have a rafting trip, train ride, or other reservation waiting for you. Follow posted signs and give road crews room to work.
Major rock blasting is complete, so daily blasting holds are no longer expected. Occasional blasting may still be needed as construction continues. Check CDOT’s latest updates for the day you’re traveling.
