Boulder County, Colo. – Due to damage, one lane of South Boulder Road is closed in both directions from South 68th Street to Barcelona Drive, just west of 76th Street.

The lane closures are expected to last for several days and will cause traffic congestion. Motorists and cyclists should use caution through the area and are advised to take alternate routes.

The damage was caused by upward heaving of the large concrete panels that make up the road. An assessment is underway to determine what caused the heaving.
