GLENWOOD SPRINGS, Colo. (KKTV) - I-70 remains closed through Glenwood Canyon Wednesday following an evening of flooding and mudslides.

❗️TRAVEL ALERT | ROAD CLOSURES - I-70 Glenwood Canyon, CO 14 Poudre Canyon and CO 133 ❗️ 🚫 I-70 Glenwood Canyon, CO 14...

That particular stretch of interstate has been a problem spot all summer in the aftermath of last year’s Grizzly Creek Fire. The burn scar runs up to I-70 in Glenwood Canyon, and the area has become prone to mudslides as a result. To prevent motorists from being in the path of a slide or rockfall, CDOT says drivers should expect that whenever rain is in the forecast this summer and fall, the chance for an I-70 closure follows. CDOT is using the following safety protocols:

1) If there is rain in the forecast but no flash flood watch or warning, CDOT may close recreation paths and rest areas in the Glenwood Canyon area but will keep the interstate open.

2) If a flash flood advisory or watch is issued, any recreation paths and rest areas not already closed will be shut down. I-70 will remain open, but CDOT crews will be put on standby in case of a mudslide.

3) If a flash flood warning is issued, I-70 will be closed through Glenwood Canyon.

Tuesday serves as a perfect example of why these protocols are used: the interstate was closed around 8:45 p.m. after a flash flood warning was issued, then the mudslides came later.

The closure extends from Rifle to Dotsero. Currently, drivers can use the following alternate route:

Westbound motorists: I-70 westbound to Silverthorne, north on Highway 9 to westbound Highway 40, then south on Highway 13 to Rifle to access I-70.

Eastbound motorists: I-70 eastbound to Rifle, north on Highway 13 to eastbound 40, then south on Highway 9 to Silverthorne to access I-70.
