BOULDER, Colo. (CBS4) – Work on Colorado Highway 119 in Boulder Canyon could continue until 2021. Last month, blasting work triggered a huge rock slide that closed the highway.

The Colorado Department of Transportation announced at a community meeting on Monday night in Nederland that work on the 15-mile stretch of the road will continue over the course of two years.

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 from 10 a.m. to 2 p.m. Monday through Thursday during blasting and other work.
