Eastman Park Drive and State Highway 257 Intersection Improvements Underway

The Town of Windsor is starting an improvement project that will have major traffic impacts at the intersection of Eastman Park Dr. and State Hwy. 257 starting mid-May and will last through early 2024. The project is intended to significantly widen the intersection, make critical railroad crossing improvements, and improve road safety and functionality.

The largest impact is anticipated to last three to four months during the summer when a small section of Eastman Park Dr. between Water Valley Pkwy./Cornerstone Dr. and State Hwy. 257 will be temporarily closed. During this time, business access will remain open and detours will be posted.

Anticipated Impacts

  • A temporary closure of Eastman Park Dr. between Automation Dr. and State Hwy. 257 while maintaining Eastman Park Dr access to State Hwy. 257 via a temporary bypass, also called a “shoofly” detour. 
  • A summer closure of Eastman Park Dr. between Cornerstone Dr./Water Valley Pkwy. and State Hwy. 257.
  • Temporary traffic signals and altered timing.
  • Pedestrian crossings and trail closures
  • Poudre Express bus stops temporarily relocated west of the current locations in order to maintain bus stop access.

Anticipated Improvements

  • Upgrades to safety and functionality.
  • Intersection widened and islands moved further apart to give trucks room to turn.
  • Improved traffic signal coordination and timing.
  • Railroad track crossing, signal and gate improvements.
  • New sidewalks and ADA accessible ramps.
  • Designated bike lanes on Eastman Park Dr.
  • Median from the Eastman Park Dr. & Water Valley Pkwy./Cornerstone Dr. roundabout to State Hwy. 257.

At the same time, the Colorado Department of Transportations (CDOT) is working to improve State Hwy. 257 from Walnut St. to Crossroads Blvd resurfacing the roadway.
