Olde Stage Road Reconstruction

Olde Stage Road Reconstruction - Retaining Walls, Culvert, Widening, & Repaving

In the summer of 2020, Boulder County Public Works completed Phase I of a major construction effort on Olde Stage Road between Lee Hill and Lefthand Canyon drives. The project had multiple components, including:

  • Two new retaining walls to provide stability for the roadway and hillside
  • A new culvert at Six Mile Creek that will increase resiliency and accommodate higher flows (photo at the bottom of page)

Starting the week of July 18, 2022, Phase II will begin and will consist a repaving project between Lefthand and Lee Hill drives that will include a wider shoulder on the south end of Olde Stage in order create a climbing lane for cyclists and provide room for emergency services. Additional drainage improvements will also be installed. Work is anticipated to be complete by the end of October, weather permitting.

Travel Impacts During Phase II

Motorists and cyclists can expect single lane closures between 8 a.m. and 5 p.m., Monday through Friday. The entire surface of Olde Stage Road surface will be milled early on during the project, so cycling conditions will be less than ideal. Alternate routes are advised. Expect delays of up to 15-minutes. Longer delays may be necessary when crews are paving at intersections. Flaggers will be used to guide travelers safely around construction zones. Driveways may be inaccessible for up to 30-minutes when crews are paving in front of them. The asphalt must be allowed to cool before cars can safely drive on it.
