Workers have broken down a huge boulder threatening to tumble down a cliff onto Interstate 70 in western Colorado and hope to have some lanes open Thursday.
State officials said they blasted the boulder just before nightfall Wednesday, but darkness prevented crews from clearing debris.
A 17-mile stretch of I-70 has been closed since Monday after the slide rained boulders onto the road and punched gaping holes in an elevated section through Glenwood Canyon, about 115 miles west of Denver.
Meantime, the State Patrol said a woman commuting to work in northwest Colorado was killed Wednesday when a basketball-size boulder fell on a car on U.S. 40, about 60 miles north of the I-70 incident.
