Drew Hill Road over Ralston Creek, Golden, CO 80403

Posted on May 10, 2022 at 2:53 PM by Lindsay Townsend

Project Background:

Jefferson County will replace a culvert (B-25-M004) on Drew Hill Road over Ralston Creek, 4.3 miles northeast of Golden Gate Canyon Road. The culvert in this location includes an existing corrugated metal pipe. The county recently had the pipe inspected and determined the existing condition of the pipe warrants replacement of the culvert.

Project Scope:

The project entails replacement of the existing corrugated metal pipe with a reinforced concrete box culvert. The box culvert will include Redi-Rock wingwalls. The project also includes installing riprap areas on the upstream and downstream sides of the culvert for erosion protection.

Project Schedule:

The project is scheduled to start in fall 2022.

Project Impact on Traffic:

During the project, the contractor will be required to provide an alternating single travel lane. The single travel lane will likely be controlled with temporary traffic signals and have minimal wait times. The county plans to provide the contractor with a single week of a complete roadway closure. This closure will only be on Drew Hill road at the project location and residents will be given notice beforehand. This will shorten the overall project length by reducing time taken to install the culvert crossing beneath the roadway.
