Important Safety Tips when Driving along Castle Pines Parkway:

As paving and additional repair work have continued, there are more construction workers out on the project site. Please take extra precautions when driving on Castle Pines Parkway.

​Some helpful tips: ​

  1. Plan extra time for your car trip to accommodate for potential delays.
  2. Minimize distractions while driving through a construction zone​.
  3. Remember to slow down and allow ample room for construction workers to perform their jobs.

Travel Impacts:

  • Construction work Monday through Friday, during the hours of 7 a.m. to 5:30 p.m. and until further notice contractor will be working Saturdays 8:00 a.m. to 4:00 p.m.
  • Full eastbound lane closures followed by full westbound lane closures after work on the eastbound side has been completed.
  • Castle Pines Parkway to remain open to single lane traffic in both directions, though alternate routes are advised due to likely delays.
  • Potential sidewalk closures on the north side of Castle Pines Parkway for pedestrians.
  • Bicycle lane closures.
  • Various neighborhood entry closures at different times during the project. Suggested alternate routes will be provided as necessary.

Project Overview

The City of Castle Pines and Castle Pines North Metro District are partnering on this joint infrastructure project to rebuild a half-mile segment of Castle Pines Parkway and replace the existing water main between Yorkshire Drive and Monarch Boulevard starting June 21, 2021. This project is just the first major component in the rehabilitation of the City's two major roads!

Project Improvements for Better Mobility and Safety:

  • Reconstruction of this stretch of roadway will replace crumbling infrastructure with a new asphalt roadway to serve the community for years.
  • Removal and replacement of aging curb and gutter to create a safer ride for bicyclists.
  • Installing 6' bicycle lanes in both directions.
  • The existing sidewalk on the north side of the parkway will be rebuilt and a new, detached 8' wide sidewalk installed.
  • All new ADA pedestrian curb ramps will be constructed providing better access for people with disabilities.


We understand that it might seem like progress is slow to be made, but we want you to know that our crews are working diligently on the northside of the road to install a new 12” underground waterline service from Yorkshire to Monarch. Once this waterline is installed, the crews can complete the remaining reconstruction of the road. Additionally, a new storm system is being installed which includes three new inlets, two new outfalls, and reinforced concrete pipe. These operations involve excavation, installation of trench boxes, laying of pipe at a minimum of 5’ below the surface, testing the piping system, and then back fill and compaction. This work can be performed with large equipment which is easier to spot than the hand work required subsurface.

The reconstruction work has encountered some minor utility conflicts that can cause some delays, however, the remaining work and completion of the project is still on schedule to be completed December 2021, weather dependent of course.
