Closures have plagued portions of I-70 in Glenwood Canyon in recent weeks as the same section was closed between July 22 and Sunday.

Weather has played a major role in the closures as the National Weather Service has issued several watches and warnings in the area. Additionally, heavy rain around the Grizzly Creek Fire burn scar has triggered mudslides and debris flows.

Although the interstate is now open to motorists, it could close again for periods of time this weekend as the forecast calls for rain. Closures depend on the weather, Colorado Department of Transportation spokeswoman Elise Thatcher said.
