I-70 Floyd Hill Project

CDOT began construction on the I-70 Floyd Hill Project, which spans from west of Evergreen to eastern Idaho Springs, in early-July 2023. Currently motorists can expect overnight lane and ramp closures on I-70. Starting in late-July 2023, the Project will begin rock scaling and blasting, which will require daytime I-70 traffic holds.

• Add a third westbound I-70 travel lane in this two-lane bottleneck. This new lane will be a full-time, tolled Express Lane from just west of Homestead Rd. (Exit 247) through the Veterans Memorial Tunnels to Colorado Blvd./Idaho Springs (Exit 241).
• Rebuild bridges due to wear and tear, and heavy usage.
• Construct a missing two-mile section of the frontage road between US 6 and the Hidden Valley/Central City Parkway interchanges, which will improve emergency response.
• Build an extended on-ramp from US 6 onto eastbound I-70 for slow-moving vehicles to have more room to merge.
• Improve traffic flow and access at interchanges and intersections.
• Improve sight distance and safety by straightening roadway curves.
• Improve the Clear Creek Greenway trail.
• Implement environmental mitigation to enhance wildlife connectivity, air and water quality, stream conditions and recreation.
• Install two permanent air quality monitors.

Rock Blasting starting in late-July with 20 minute traffic holds and up to 45 minute delays Monday through Thursday from 9am to 3pm.
