The City of Centennial has selected Hamon Infrastructure for the $9.5 million Arapahoe Road reconstruction project.
Arapahoe Road, between Waco Street and Himalaya Way, is currently a two-lane roadway designed to handle 20,000 vehicles per day, but currently handles about 23,900 vehicles per day with significant peak hour volumes. Traffic along this busy segment of Arapahoe Road is anticipated to further increase in the coming years. The City of Centennial, along with project partners Arapahoe County, Southeast Metro Storm Water Authority (SEMSWA), and the City of Aurora, are collaborating on a plan to increase capacity and improve safety and mobility through this segment of the corridor.
About 1.5 miles of Arapahoe Road between Waco Street and Himalaya Way will be reconstructed and widened from the existing two-lane section to an interim four-lane section, with six-lane sections on the east and west ends. Three existing signalized intersections will be replaced with new signals. Several existing drainage outfalls along the project will be redesigned and constructed in coordination with the Southeast Metro Storm Water Authority (SEMSWA). Additionally, overhead electric lines on both sides of Arapahoe Road will be relocated to accommodate the ultimate roadway section. The design will be coordinated with Intermountain Rural Electric Association (IREA).
The new, interim 4-lane roadway will:
- Be straighter and easier to navigate;
- Provide easier left turn movements onto the roadway; and
- Enable easy, gradual transitions from six lanes to four lanes and back to six lanes
This construction project will be completed in late 2016.
