Overnight eastbound I-70 closure near Idaho Springs for paving and restriping

Clear Creek County - Motorists can expect an overnight closure of eastbound Interstate 70 between Idaho Springs (Exit 241) and Hidden Valley/Central City Parkway (Exit 243) for paving and restriping operations on the I-70 Floyd Hill Project, the night of Nov. 10. This work will finalize the eastbound I-70 traffic shift that took place last week, shifting eastbound I-70 north onto the completed bridge over Clear Creek. Motorists can stay informed on the upcoming closures by signing up for text alerts by texting floydhill (one word) to 21000.

Full closure of eastbound I-70
Crews will require an overnight closure of eastbound I-70 between Idaho Springs (Exit 241) and Hidden Valley/Central City Parkway (Exit 243).

• 9 p.m., Tuesday, Nov. 10, to 5 a.m., Wednesday, Nov. 11

Detour: Eastbound I-70 motorists will merge into one lane and use the eastbound I-70 off-ramp to Idaho Springs (Exit 241), and then travel east on County Road 314 to access eastbound I-70 at Hidden Valley/Central City Parkway (Exit 243).

All work is weather-dependent and subject to change. If weather or unforeseen circumstances impact this work, crews will shift the closure schedule, and the eastbound I-70 closure could occur from 9 p.m. Thursday, Nov. 12, to 5 a.m., Friday, Nov. 13.

Traffic hold needed for bridge demolition
At approximately 1 p.m. Wednesday, Nov. 11, motorists can expect a 20-minute traffic hold on I-70 between Idaho Springs (Exit 241) and US 6 (Exit 244) for crews to conduct a blasting operation to demolish the existing eastbound I-70 bridge over Clear Creek. Traffic will also be held on County Road 314, Central City Parkway and US 6 and US 40. Stay the course on I-70 - there is no detour. Plan for a delay of up to 45 minutes as the traffic queue clears. Stay tuned to Project text alerts for information on the upcoming blast.

In mid-November, motorists can expect two overnight, westbound I-70 closures at US 6 (Exit 244) for segmental bridge construction. During the westbound I-70 closures, crews will grout the tendons on the concrete segmental bridge.

From early-to-mid December, motorists can also expect a series of overnight eastbound I-70 closures at US 6 (Exit 244) for segmental bridge construction. During the eastbound I-70 closures, crews will install a movable platform, called a form traveler, at the bridge column over eastbound I-70 near US 6. The form traveler will help crews construct the bridge, segment-by-segment.

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 creating safer wildlife movements.

Construction began in July 2023. I-70 will be in its new alignment in 2028, with the entire project expected to conclude in 2029.
