2026 Castle Pines Parkway Reconstruction

Project Overview

As a part of the 2026 Road Solutions projects, road reconstruction will begin on June 1 for the westbound lanes of Castle Pines Parkway. The project will include a complete reconstruction of the roadway. The Castle Pines North Metropolitan District will also replace the water line under the road and the related water infrastructure. This project marks a significant investment in Castle Pines’ infrastructure, enhancing safety, increasing mobility, and upgrading critical utilities.

Schedule:

  • Project Start: June 1, 2026
  • Anticipated Project Completion: Early fall 2026
    • Crews are scheduled to complete the section from Monarch Boulevard past Timber Trail Elementary during the summer to limit impacts on school traffic.

Project improvements include:

  • Reconstruction of the westbound lanes of Castle Pines Parkway between Monarch Boulevard and Forest Park Drive.
  • Diamond grinding from Forest Park Drive to Buffalo Trail to smooth the existing roadway and improve drivability.
  • New water line and related infrastructure by the Castle Pines North Metropolitan District.

Detour Information and Construction Impacts:

  • Traffic is planned to be rerouted so that both westbound and eastbound traffic uses the eastbound traffic lanes on Castle Pines Parkway.
  • During the initial phase of construction, crews will replace waterline infrastructure in the Castle Pines Parkway and Monarch Boulevard intersection. During this work, lane shifts will be required. However, turning movements in all directions will remain open. Please drive carefully, follow construction crews' directions, and pay attention to construction signage and cones. Lane shifts will change throughout this phase of the project.
