A section of Interstate 70 near Glenwood Canyon in Colorado is shut down due to the Grizzly Creek Fire.

According to the Colorado Department of Transportation, I-70 is closed from mile marker 116 to mile marker 140. Both westbound and eastbound directions are shut down because of the Grizzly Creek Fire. CDOT recommends the following detours:

  • Travelers heading westbound on I-70 can use U.S. 24, CO 91 or CO 9 to US 285/US 50 and continue west.
  • Motorists headed east on I-70 can travel on U.S. 50 to travel east towards US 24, CO 91 or CO 9 to return to I-70 eastbound, or continue east on US 285 to the Denver metro area.
  • Motorists can take a northern detour of CO 131 to U.S. 40 to CO 139.

While CO 13 is open, it is not a recommended detour due to construction. Also, oversize commercial vehicles are not allowed due to construction conditions on CO 13.

CDOT is also asking motorists to not use Cottonwood Pass because of Grizzly Creek Fire activity.

Motorists should expect delays as alternate routes are not accustomed to carrying traffic volumes as heavy as I-70.
