US 160/US 550 Durango Continuous Flow Intersection

Traffic Impacts:  July 28-August 1

The work zone is expected to be very busy as the project team focuses on completing the raised islands and medians as quickly as possible. Motorists should use caution when approaching the intersection, particularly when using the new signal and turn lane, and maintain the posted speed limit of 35 mph.

Travel impacts for the week of Monday, July 28 through Friday, August 1:

  • No Weekend Work Anticipated July 26 & 27
  • US 160 and US 550: Median and single-lane closures and two lane shifts likely throughout the week, all directions. Single-lane closures are anticipated during non-peak travel times from 8:30 a.m. to 4:30 p.m. and after 6:30 PM.
  • Side Streets (from CFI intersection to 9th Street): Minimal and intermittent impacts as crews finalize striping and signage.
  • US 160, Tech Center to the CFI Intersection: Expect lane, median and turn-lane closures: westbound, single-lane closures are possible anytime; eastbound, single-lane closures are anticipated during non-peak travel times from 8:30 a.m. to 4:30 p.m. and after 6:30 PM.
  • Roosa Avenue: Expect northbound lane closures during day and evening hours – there will be no left turns from eastbound US 160 onto Roosa Ave.

Please see lane closure reports HERE for more specific travel impact information, updated each Friday (click on SW Colorado).

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.

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.
