Highway 9 Closure in Southeastern Colorado: What Travelers Need to Know

ALMA, COLORADO — A vital bridge structure on Colorado Highway 9 (CO 9), north of the town of Alma, is undergoing full replacement, which has led to a 7-day closure. The Colorado Department of Transportation (CDOT) in collaboration with the prime contractor, CapitalTezak Joint Venture, initiated the closure on September 7th at 6 a.m. and it is slated to run continuously until September 14th at 6 a.m.

The closure is a part of the Region 2 Bridge Bundle project, initiated in 2022, aimed at modernizing and securing 17 aging structures across rural highway corridors in the state. The ongoing project is budgeted at $43 million and is expected to complete by late 2024.

The existing bridge structure at Mile Point 71.5, located between County Road 6 and County Road 4, was originally built in 1938. Deemed structurally deficient and functionally obsolete, the bridge is now being replaced with an aluminum box culvert. The material expedites construction while also ensuring a lifespan of 100 years for the new structure.

During the closure period, all traffic will be rerouted through U.S. 24, CO 91, and I-70. According to CDOT, travelers can expect an additional 120 miles and approximately 2 hours and 25 minutes added to their journey. For up-to-date traffic information, you can visit

Hi, I'm Alex!

In 2018, I watched in disbelief as dozens of people hiked into a storm on Longs Peak, unaware of the extreme danger. Soon after, I started The Next Summit to educate and empower the public to safely and responsibly explore America's mountains.
