US 50 & CO 231 Improvements - Construction

About the Project:

The Colorado Department of Transportation successfully completed the design phase for intersection improvements at both US 50 and CO 231 (36th Lane) and at US 50 Business and CO 231 (36th Lane) in Pueblo. After a thorough evaluation, the design was finalized with the aim of enhancing safety by increasing sight distance to facilitate secure motorist crossing of US 50 and to improve overall pedestrian and motorist safety near schools along US 50 and 36th Lane.

In advance of the construction phase, the following improvements were made to the intersections after the study was completed:

  • The speed limit was reduced approaching the intersection on US 50 Business and 36th Lane.
  • Existing signage was repositioned to improve sight distance at both intersections.
  • Advanced guide signs were relocated ¼ mile before the US 50 and 36th Lane intersection.
  • Pedestrian signs were updated and replaced at US 50 Business and 36th Lane and a rapid flashing beacon sign was added to alert motorists and pedestrians.

Construction of US 50 and CO 231 (36th Lane) will have design improvements that include:

  • The stop line of CO 231 (36th Lane) at US 50 Business will be moved up to the travel lanes of US 50 Business to reduce the crossing distance for northbound and southbound left turning vehicles.
  • Raised islands will be installed with pedestrian refuge that allows the stop line to be moved up and improves sight distance when crossing the intersection.

Construction of US 50 and CO 231 (36th Lane) will have design improvements that include:

  • The right thru lane of US 50 eastbound will convert into a right turn only lane ½ mile in advance of the intersection with 36th Lane.
  • An intersection conflict warning system that will recognize approaching traffic and illuminate the warning signs alerting motorists of approaching vehicles to the intersection on both US 50 and on CO 231 (36th Lane) will be installed.
  • The stop line of CO 231 (36th Lane) at US 50 will move up to the eastbound lane of travel so the right turn lane will not impact the view of motorists trying to cross the intersection. This will also reduce the crossing distance for northbound left-turning vehicles.
  • Raised islands will be installed to allow the stop line to be moved up and will improve the sight distance when crossing the intersection.
