A series of winter storms that dumped up to 6 feet of snow over four days in the San Juan Mountains led to several road closures in the region, but receiving up-to-date information of those closures proved difficult during the blizzard.

The Colorado Department of Transportation maintains several alert systems to give drivers timely updates on road conditions and closures throughout the state, including a travel-information phone number (511), electric signs on the side of the road, a website with real-time information, and email, text and social media notifications.

But coordinating all of those systems can be tricky, said CDOT spokeswoman Nancy Shanks. With a big storm, breakdowns in communication can occur, and travelers sometimes receive unclear or contradictory information, she said.

“CDOT certainly can get things wrong,” she said. “We need to be a well-oiled machine. There are a lot of people dealing with a lot of information. We definitely strive to get it right.”
