GRAND JUNCTION, Colo. (KKCO/KJCT)-- Part of I-70 has been closed for three days after a rock slide shut down the interstate on Sunday.
C-DOT workers were hoisted up to the cliffs in the area of mile marker 57 on I-70 eastbound.
Their goal was to prevent future rock slides from happening, by blasting away unstable parts of the cliffs.
Some rocks that fell on Sunday were reported to be similar size to small cars.
Officials estimate about 70-tons of rock fell down by the roadway, and their goal was to remove a similar amount with the rockfall mitigation.
While the blast sent rocks flying down below, officials say its the quickest, and safest way to get the job done.
"It allows them to take larger masses down at one time, rather than sort of, disassembling a Jenga tower where your not sure what might come down, so its actually safer for the guys on the slope as well, said CDOT Geological Engineer, Bob Group.
CDOT says they hope to have the eastbound lanes of I-70 back open by Thursday, May 9th, or Friday, May 10th.
The detour set up at Exit 49 to Highway 65 is still in place, and drivers can get back on the interstate in Debeque.
