As a response to the popularity of the ongoing texting campaign for the I-70 Floyd Hill Project, which has reached nearly 15,000 subscribers, the Colorado Department of Transportation is expanding text alerts to cover two additional key areas along the I-70 Mountain Corridor: the I-70 West Vail Pass Auxiliary Lanes Project and the I-70 Mountain Express Lanes.

Motorists can sign up to receive lookaheads and live updates on planned traffic holds for the I-70 Floyd Hill and I-70 West Vail Pass projects, and notifications on unexpected closures and delays for the I-70 Mountain Express Lanes, according to a CDOT news release.

How to sign up: 

Motorists can opt in or out of specific alerts based on travel needs. For each project of interest, text the assigned one-word terms to the number 21000.
