US 6 Over Garrison Street

From early 2015 to summer 2016, CDOT replaced a structurally deficient bridge that carries US Highway 6 traffic over Garrison Street in Lakewood.

The work on this bridge was procured as a streamlined design build project, a process which encourages innovation and delivers a fast, standardized, and efficient procurement solution for both CDOT and for the design build industry.

About the Bridge

The former bridge structure on US 6 over Garrison Street was deteriorating and was rated as "poor," with a sufficiency rating of 32 out of 100. The original structure was built in 1962 and widened to the center in 1972. The new bridge has a 75-year design life, and it will improve the safety of intersection as well as provide a number of community benefits.


  • Driver safety will increase due to improved sight distances on US 6.
  • New sidewalks and bike-lanes along Garrison Street will improve pedestrian access and safety in the area.
  • Signal improvements will improve traffic flow at US 6 and Garrison Street.
  • Aesthetic enhancements include new architectural walls and an improved bridge design.
  • Added lighting for pedestrians and bicyclists under the bridge will improve safety and contribute to the beautification of the intersection.
  • Improved drainage will provide safety and aesthetic benefits.
  • The accelerated project schedule delivered community benefits in the least amount of time.
