Project Background

Public Works is set to perform a full-depth reconstruction of W. Union Ave. from Santa Fe Blvd. east to the bridge over the South Platte River. Due to the high volume of heavy vehicles on this street, a complete reconstruction is necessary to accommodate the traffic and address the underlying subgrade issues. All work will occur within the existing edges of the road, and gutter and sidewalk improvements are not part of this project.

Project Location: W. Union Ave. from Santa Fe to South Platte River.


Project Goals

The current road conditions pose a hazard to drivers and generate significant noise from heavy vehicles. One goal of this project is to rebuild the road to better accommodate heavy vehicle traffic, using a combination of Polymer modified Hot Mix Asphalt and concrete materials that will help reduce noise and improve road conditions. Another goal is to strengthen the subbase, ensuring the street has a longer lifespan than the current conditions allow.

Project Timeline

The city has awarded the construction contract to Asphalt Specialties Company, Inc. Construction is planned to begin in late March to early April of 2026.

Local businesses will be contacted late February 2026 and also again 48 hours prior to work commencement.

    Construction on the West Union Avenue Pavement Replacement Project is expected to begin in the coming days. Residents and travelers in the area should anticipate lane closures and the presence of heavy equipment as crews mobilize and begin work.

    This project will reconstruct West Union Ave. from Santa Fe west to the bridge over the South Platte River. Because this corridor carries a high volume of heavy vehicles, crews will complete a full-depth reconstruction of the roadway to address underlying subgrade issues and create a stronger, longer-lasting street.

    The project is expected to be completed by early summer. Once finished, the improvements will provide a more durable roadway designed to better handle heavy traffic, reduce the need for frequent repairs and keep this important connection safer and more reliable for the community.

    Xcel Energy and their contractor, Centerline Energy, will be relocating a gas line beginning the week of February 16. They anticipate the relocation process will take around 3 weeks. One lane of access on Union will remain open at all times, and they do not anticipate any disruption to gas service.

    This relocation is necessary before beginning work on the Pavement Replacement Project, which is still slated to begin in mid to late March.
