The Floyd Hill project will lead to traffic holds and overnight closures on Interstate 70 during the last two weeks of June, the Colorado Department of Transportation said in a news release.

To remove loose rock on the north side of I-70, east of the Hidden Valley/Central City Parkway interchange at Exit 243, crews will be performing rock scaling for eight days over the two weeks, the release states. Operations will reportedly run from 9 a.m. to 3 p.m. Mondays through Thursdays for the two week period beginning Monday, June 16.

Drivers should expect several traffic holds per day, approximately every hour, on I-70 between the Veterans Memorial Tunnels and Homestead Road at Exit 247, the release states. Delays of up to 45 minutes could occur as traffic clears, including delays that could extend past 4 p.m. Motorists should remain on I-70 during the traffic holds as there is no detour, according to CDOT.

Two full overnight closures of westbound I-70 will also be required for sign installation between County Road 65 at Exit 248 and U.S. Highway 6 at Exit 244, the release states. The closures are planned from 10 p.m. Monday, June 16, to 4:30 a.m. Tuesday, June 17, and from 10 p.m. Monday, June 23, to 4:30 a.m. Tuesday, June 24.

For the overnight closures, westbound I-70 traffic will merge into one lane and exit at County Road 65, head west on U.S. Highway 40 and use the U.S. Highway 6 on-ramp to return to westbound I-70, the release states.
