Boulder Canyon reopens after landslide

The canyon is closed from the base in Boulder to the top of the canyon in the Netherlands.

BOULDER, Colo. – Colorado Route 119 through Boulder Canyon reopened Wednesday night following a major rock slide that closed the artery for more than a day.

The rockslide occurred Tuesday around mile marker 32 in an area known as the Narrows, the Colorado Department of Transportation (CDOT) said. The damage caused the closure of the highway from the base of Boulder to the top of the canyon in the Netherlands.

No one was injured and no cars were damaged, CDOT said. The slide happened during heavy rain and snow.

In the hours that followed, crews had to truck around 300 to 500 cubic meters of rock from the road. To put that into perspective, one cubic meter of rock is roughly the size of a dishwasher.

“The road is still rough in some areas, so drivers are advised to drive slowly,” CDOT said in a press release.

A permanent pavement repair is expected to take place in the “near future”.

CDOT said its geological teams have assessed the area where the rockslide occurred to ensure it is safe from another rockfall. The landslide occurred in the same area where the agency is working on permanent repair from the 2013 flood.
