Arapahoe Road Widening from Waco to Himalaya

Centennial, CO

This was a multi-agency funded road-widening project on Arapahoe Road, a major east/west arterial serving the City of Centennial, City of Aurora, and Arapahoe County. To increase capacity and ease traffic delays, the two-lane roadway was widened to a four-lane section while allowing for an ultimate six lane build out in the future. The roadway widening included a triple 10’x12’ box culvert constructed at Antelope Creek as part of the Piney Creek SEMSWA drainage plan and a 24” water main with ACWWA partnership. The Benesch team provided construction management and full-time observation, in-depth schedule review, materials testing (Geocal), and quality assurance surveying. Because many residents and businesses were directly impacted by the project, Benesch also worked with the City’s and Contractor’s public involvement groups to coordinate construction activities with locals and provide regular public updates throughout the project.
