US 160/US 550 Durango Continuous Flow Intersection

Traffic Impacts:

The project is expected to last through mid-August 2014. However, CDOT and contractor Concrete Works of Colorado are on schedule to complete work items north of the US 160/550 intersection (in the more congested urban area) by Memorial Day weekend, prior to the summer tourist season. After that, the work zone will shift south of College Drive on US 550 and west on US 160.

Single-lane closures through the work zone, from south and west of the intersection and north to 9th Street, are in effectMonday through Thursday, 8:30 a.m. to 4 p.m. and on Fridays until 2 p.m. No weekend work is currently anticipated. Travel delays may exceed 15 minutes at times, depending on traffic queues and time of day.

Please drive cautiously through the work zone, for everyone's safety. It's important to note that lane closures are necessary to enable crews to improve this stretch of highway--the work zone and resulting traffic impacts are temporary. The highway safety and mobility improvements for all users will last for decades to come.

More information about travel impacts will be sent to those signing up for updates and posted on this project web site; or check CDOT's weekly lane closure report here and click on SW Colorado.

Project Overview:

The Colorado Department of Transportation (CDOT) began work on its first Continuous Flow Intersection (CFI) project on Monday, March 17, 2014, at the US 160/550 west intersection in Durango. The CFI is a proven and promising approach to reducing congestion and increasing safety at high-traffic intersections, based on other CFIs constructed nationwide. 

A CFI effectively removes a left-turn movement from an intersection by re-configuring the highway to allow vehicles to cross to the left side of the highway in advance of the intersection, allowing for additional concurrent traffic movements that are not possible at a conventional signalized intersection. These additional concurrent movements increase signal efficiency and provide the opportunity for longer green times for southbound and eastbound movements. Vehicles traveling northbound on US 550 (from Walmart, for example) turning left onto westbound US 160 (to Cortez) will utilize a new signal to turn in advance of the current stoplight, cross southbound traffic to a new separated cross southbound traffic to a new separated lane, and complete their turn onto US 160 from the new lane.

This intersection sees 30,000 to 45,000 vehicles each day, depending upon the season. That is more motorized traffic than any state highway on the Western Slope (including I-70) and about the same amount of traffic as the busiest state highways in Greeley.

Other project details include:

  • Improved bicyclist transportation with bike lanes, bike boxes, green pavement markings, signing, and bicycle-capable signal detection;
  • Improved pedestrian transportation with median refuges, shortened roadway crossing distance through raised curbed islands and medians, raised crosswalks, signing and rectangular rapid flash beacons;
  • The total construction cost of the CFI is estimated at $6.1 million.
