While only a little snow fell in Southern Colorado, areas around Denver and in the mountains experienced pockets of heavy snow, causing road closures and long delays.
Around 2 p.m. CDOT closed U.S. Highway 50 at Monarch Pass west of Salida due to multiple crashes and it closed U.S. Highway 160 at La Veta Pass, which is between Walsenburg and Alamosa.
As of 3:00 p.m.: US 50 Monarch Pass open in both directions, chains required for all CMVs

Earlier in the day, I-70 also saw its share of traffic problems.

A "major crash" shut down all lanes of I-70 west of Denver a little before 9 a.m. Monday morning, causing traffic delays and significant back-ups. Westbound lanes of the interstate were reopened around 9:50 a.m. Monday morning, with all eastbound lanes opening a little later. Mutliple crashes near Boulder also shut down Highway 119.
Further to the northwest, mountain passes near Steamboat Springs saw several inches of snow.
It’s winter on Rabbit Ears Pass again. The highway is snow packed and icy. CDOT is readying to make another pass on the Pass. Slow down! pic.twitter.com/KobQP8PzRF— CSP Craig (@CSP_Craig) October 9, 2017
Meanwhile, traffic was a little slow in the Denver metro area, but most of the snow that fell did not immediately stick to the roads. Flights at DIA did not experience significant delays, but delays averaged about 16 minutes for deicing.
