Cottonwood consternations: Residents weigh in on plans to improve route that serves as de facto I-70 alternate during Glenwood Canyon closures  


For years, the 12-mile-long stretch of I-70 has been prone to rockfalls and vehicle crashes that tend to close the highway for long periods of time throughout the year, but most often in the winter when Cottonwood Pass is closed.

Then came the Grizzly Creek Fire in August 2020, followed by the massive mud and debris flows after heavy rains pounded the burn scar last summer. 

Both events resulted in weeks-long closures of I-70 through the canyon, and now every time the National Weather Service issues a flash flood warning for the area, the highway closes again.

How to mitigate slides in canyon?

Whether it is the use of chutes or other preventative measures, it would seem that it is time for CDOT to make a determination of what other measures should be taken to harden the canyon from further slides and resultant closures because there are no other practical alternate routes for commercial trucking.  Karen Moculeski

Last year, when the canyon shut down for two weeks, the National Guard was mobilized to help thousands of tourists inch their way over the pass, which navigation apps recommended as an alternative route to shave hours off the official detour. The cat was out of the bag. This is no reason to let it have kittens.
