Boulder highway reopened after closure from rock fall

BOULDER |  A Colorado state highway in the foothills west of Boulder has partially reopened to traffic after blasting work triggered a huge rock slide that closed the highway.

The Colorado Department of Transportation announced that Colorado 119 opened about 4 a.m. Thursday with one lane of alternating traffic.

Huge rocks tumbled onto the highway in Boulder Canyon Wednesday. The road was closed at the time of the blast and no injuries were reported.

The blasting is part of a project to move more of the highway onto bedrock to protect from it flood damage. That work will continue, with scheduled closures of the highway during blasting.

CDOT says no closures are expected for Friday or over the weekend. Regular blasting closures will resume at 10 a.m. Monday.
