I-70 Floyd Hill Project Update

The Colorado Department of Transportation’s I-70 Floyd Hill Project continues construction on the East Section of the project, which spans I-70 from County Road 65 to the bottom of Floyd Hill (approximately exits 248 to 244). 

Motorists can continue to expect traffic holds approximately every 75 minutes between 9 a.m. and 3 p.m., Monday through Thursday, on I-70 and US 40 between Homestead Road (Exit 247) and the US 6 (Exit 244) interchanges, which could result in up to 45 minutes of delay as rock scaling and blasting work continues. During the traffic holds, we recommend you turn off your vehicle to help with air quality. For updates on rock scaling and rock blasting, text floydhill (one word, lowercase) to 21000. 

Rock Scaling and Blasting Traffic Impacts

• 9 a.m. to 3 p.m., Monday, Aug. 21, through Tuesday, Aug. 22 - Crews continue rock scaling operations between the Homestead Road (Exit 247) and US 6 (Exit 244) interchanges. Crews will scale rocks multiple times a day during off-peak travel hours. 
• Noon to 3 p.m., Wednesday, Aug. 23, and Thursday, Aug. 24 - Crews continue rock scaling operations between the Homestead Road (Exit 247) and US 6 (Exit 244) interchanges. Crews will scale rocks multiple times a day during off-peak travel hours. 
• Noon to 2 p.m., Tuesday, Aug. 22, and Thursday, Aug. 24 - Crews will use one of the planned scaling operations to also conduct a rock blasting operation. Crews will blast once a day and up to two times per week. A series of airhorn blasts will precede each detonation to warn people in the area. 
• Crews will wait until traffic is flowing at normal speeds before continuing with rock scaling operations. 

I-70 Ramp Closures

• 6 p.m., Wednesday, Aug. 23 to 6 a.m., Thursday, Aug. 24 - The Homestead Road on-ramp to westbound I-70 (Exit 247) will be closed for roadway repairs. Detour: Continue west on US 40 and use the US 6 interchange (Exit 244) for access to westbound I-70. 

• 6 p.m., Wednesday, Aug. 23 to 6 a.m., Thursday, Aug. 24 - The eastbound I-70 off-ramp to Homestead Road (Exit 247) will be closed for roadway repairs. Detour: Continue on eastbound I-70, turn around using the El Rancho interchange (Exit 251) and then use the westbound I-70 off-ramp to County Road 65 (Exit 248) and US 40 to access Homestead Road.

I-70 Lane Closures

• Lane closures on westbound I-70 between County Road 65 (Exit 248) and US 6 (Exit 244) for roadway repairs. 
  • 9 p.m., Sunday, Aug. 20 to 6 a.m., Monday, Aug. 21
  • 9 p.m., Thursday, Aug. 24 to 5 a.m., Friday, Aug. 25
• 6 p.m. to 6 a.m., Monday, Aug. 21, through Thursday, Aug. 24 - Watch for lane closures on eastbound I-70 between US 6 (Exit 244) and County Road 65 (Exit 248) for roadway repairs.

I-70 Mountain Corridor-Wide Traffic Impacts

• Reduced speed limits as low as 45 mph, narrower lanes and shoulders, and increased truck traffic entering and exiting the work zones. Heed the speed limit, do not follow trucks into the work zone, go slow for the cone zone and do not drive distracted. 
• Motorists should expect daytime and nighttime shoulder closures on westbound I-70 for utility work. 
• All construction activities are weather dependent and subject to change. For real-time travel information, visit COTrip.org.

About the Project

The I-70 Floyd Hill Project will improve eight miles of the I-70 mountain corridor, from west of Evergreen to eastern Idaho Springs. The Project will deliver a third westbound I-70 travel lane, which will function as an Express Lane, to improve the current two-lane bottleneck. Other major elements include constructing a missing two-mile section of the frontage road between Evergreen and Idaho Springs, building an eastbound I-70 extended on-ramp for slow-moving vehicles, improving traffic flow and access at interchanges and intersections within the project limits, improving sight distance on roadway curves, improving the Clear Creek Greenway trail, and implementing environmental mitigation to create safer wildlife movements and improve air and water quality, stream conditions and recreation.

Construction began in July 2023 and is expected to conclude in late 2028.
