Rockslide closes I-70 at mile marker 46 near Grand Junction

GRAND JUNCTION, Colo. - A rock slide has closed Interstate 70 in both directions in western Colorado, but no injuries were reported.

The Colorado Department of Transportation says a boulder -- at least 8 feet by 8 feet -- and debris tumbled onto eastbound lanes east of Palisade, near exit 46, Wednesday. Smaller rocks fell on westbound lanes.

The detour around the slide takes about 90 minutes because of the distance between roads in the area. The closure could last hours.

A contractor plans to break up the boulder with explosives and haul it away. Workers are also dislodging other loose rock on a cliff above the highway.

The slide is 18 miles east of Grand Junction and 225 miles west of Denver.

Another slide closed one lane of Colorado 82 between Aspen and Independence Pass but caused no injuries.
