Intermittent Closures May 23-24 on I-70 at Fall River Road for Rockfall Work

Blasting complete; further scaling work required to complete job

IDAHO SPRINGS—From 8:30 a.m. to 4:30 p.m. on Tuesday, May 23 and Wednesday, May 24, motorists can expect 20-minute closures on eastbound and westbound I-70 from Fall River Road to Dumont. During this time, crews will be scaling a rock face to prevent rock slides on I-70 near Idaho Springs.

Traffic will be held for 20 minutes, and then released, clearing traffic before closing lanes again.

The remaining work does not require blasting. Two rounds of blasting earlier this month at the rockfall site were successful in removing overhanging rock. CDOT's geo-hazard group identified potentially loose rock that requires scaling.

There will be no work or lane closures on Memorial Day week. Work will resume the week of June 5, requiring a right lane closure for one to two days to install a rock fence. Rockfall mitigation work will be completed by mid-June.


CDOT is conducting mitigation work in response to a minor rockslide that occurred in April on westbound I-70 at Fall River Road. CDOT's geohazards team inspected the slide and determined that mitigation work is necessary to reduce the risk of a slide in the same area in the future.
