Additional overnight single-direction closures of I-70 needed for I-70 Floyd Hill Project’s segmental bridge construction

Clear Creek County - Motorists can expect a few more overnight, single-direction eastbound and westbound Interstate 70 closures at the US 6 (Exit 244) interchange as the Colorado Department of Transportation’s I-70 Floyd Hill Project continues with bridge work over I-70. To finish installing a movable platform, called a form traveler, at the bridge column over westbound I-70 at US 6, crews require two additional westbound I-70 closures this week. The form traveler will help crews construct the bridge, segment-by-segment.

In addition to the westbound I-70 closures, crews will shift the eastbound I-70 closures originally planned for this week to later this week and into early next week to finish removing the temporary framework structure at the bridge column over eastbound I-70 near US 6. This work is part of segmental bridge construction, which will carry westbound I-70 in its new alignment.

The updated westbound and eastbound I-70 closures schedule is:

  • Overnight Westbound I-70 Closures:
    • 9 p.m. to 5 a.m., Wednesday, Aug. 19, through Thursday, Aug. 20
  • Overnight Eastbound I-70 Closure:
    • 9 p.m. to 5 a.m., Friday, Aug. 21, Monday, Aug. 24, and Tuesday, Aug. 25

All work is weather-dependent and subject to change. For reminders on the I-70 closures and to stay informed, sign up for text alerts by texting floydhill (one word) to 21000.

Westbound I-70 detour: Westbound I-70 traffic will merge into one lane and use the US 6 (Exit 244) off- and on-ramps to continue on westbound I-70.

Eastbound I-70 detour: Eastbound I-70 traffic will use the eastbound I-70 off-ramp to US 6 (Exit 244) and then travel east on US 40 to access the County Road 65 (Exit 248) on-ramp to return to eastbound I-70.

Once crews install the form traveler on the bridge column over westbound I-70 near US 6, crews will begin building the segmental bridge outward over I-70, piece by piece.

Project Information

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.
