About a mile of Heeney Road north of Heeney will see closures Monday through Friday starting Aug. 4, according to a Summit County news release.

The closure, needed for crews to perform rockfall mitigation work, will start near County Road 1812 and end near the Big Green Day Use Area without restricting access to either. The release stated the closures will last six to eight weeks, and the road will be closed day and night Monday through Friday, reopening on the weekends as conditions allow.

Those traveling to Heeney from the north will be the most affected, the release stated, as they will need to take a 20-30 minute detour to the south entrance of Heeney Road off Colorado Highway 9 closer to Silverthorne.

Steve Greer, the deputy county manager overseeing Summit County Public Works, said in the news release that rock scaling projects create safety concerns for travelers and work crews.

“Closures like this can be extremely inconvenient but are necessary to protect the traveling public and construction workers,” Greer stated.

He added that keeping the road closed throughout the work week will help crews finish the project by the fall.

The Big Green Boat Ramp and Willows Campground will be accessible from the north, and CR 1812 and the Heeney Marina will be accessible from the south.

The release stated the project will mitigate the risk of falling rocks and address other safety concerns for five to seven years. Funded by a Colorado Department of Transportation grant of around $500,000, the project will remove a “significant volume” of rock from the hillside.
