Eastman Park Dr. and State Hwy. 257 Intersection Improvements Underway

The Town of Windsor is starting the intersection improvement project at Eastman Park Dr. and State Hwy. 257 that is anticipated to have major traffic impacts mid-May through early 2024. The project is intended to significantly widen the intersection, make critical railroad crossing improvements, and road safety and functionality. The largest impact is anticipated to last 3-4 months during the summer when a portion of Eastman Park Dr. between Water Valley Dr./Cornerstone Dr. and State Hwy. 257 is temporarily closed. Business access will remain open, but residents are encouraged to detour.
The Colorado Department of Transportation (CDOT) will be working on roadway improvements along areas of State Hwy. 257 in tandem with the intersection improvements. CDOT will be resurfacing the roadway between Walnut St. and Crossroads Blvd. For updates specific to CDOT's project, visit Text 257 to 866-762-3640 receive text notifications.

The Town of Windsor is continuing the intersection improvements at Eastman Park Dr. and CO 257 and is nearing completion. Over the past several weeks, the intersection has been paved from the roundabout at Cornerstone Dr. to CO 257. Additionally, the signal poles and railroad gates have also recently been installed and currently undergoing wiring. For the intersection to fully open to traffic, the roadway needs to be striped, roadway signs need to be installed and the final inspection needs to be passed. The intersection is anticipated to open before the end of September, weather permitting.

Once the intersection is opened back up to traffic, shoulder and sidewalk work will continue. Residents are encouraged to remain vigilant when traveling through the work area. For more information, visit For traffic alert notifications, text Roads to 970-251-7151.

CDOT is continuing their CO 257 roadway improvements from Crossroads Blvd. to US 34. For updates and more information, visit To receive CDOT’s traffic alerts, text 257 to 866-762-3640.

August 25, 2023 4:25 PM

As of Thursday, August 24, both the northbound and southbound portions of CO 257 at the intersection of Eastman Park Dr. are open. Same goes for CDOT’s floodplain closure. Following the reopening of CO 257, the Town of Windsor will focus on paving Eastman Park Dr. between Cornerstone Dr. and CO 257, coordinating the Railroad signal and safe crossing installation, and installing traffic signal poles at the intersection for the east/west portion to reopen.

Before the traffic signal poles can be installed, there is a couple weeks’ worth of wiring, on-site assembly and preparation that has to go into the street corners so they can stand up on their own. The town also has to coordinate with the railroad so their crossing signals are in sync with the new traffic lights. While the details are still being worked out logistically, the town is aiming for an October intersection reopening. Text Roads to 970-251-7151 to receive traffic alerts.

Then, starting Tuesday, Sept. 5, CDOT is going to fully close a portion of CO 257 south of Crossroads Blvd. for 20 days for bridge repairs. We mentioned this closure at the beginning of this project, so we hope it’s not catching you off guard. If it is, you can find more information about their road work at or text 257 to 866-762-3640.

All road work is weather permitting and subject to change.

The intersection will be open to traffic on Thursday, July 20 on a temporary gravel surface. During the week of Monday, July 24, work on the final top layer of pavement along CO 257 will begin. While the final layer of asphalt is installed along CO 257, there will be intermittent, short-term closures of the Garden Dr. intersection while the construction crew paves through in each direction.  During this time, business access will remain open, and residents will have to detour via Automation Dr. or CR 23.

Garden Intersection Closure
June 30, 2023 3:26 PM

Starting June 5, CO 257 will be closed from the roundabout north of Walnut St. to Eastman Park Dr. The closure is anticipated to last 30 days and crews will be working six days a week, weather permitting. Commuters will have to detour and businesses will remain open.

Due to the historic precipitation Windsor experienced in May and June, both CDOT’s and the Town of Windsor’s roadway and intersection improvement projects have seen significant delays. The closure is intended to catch up on lost time without having to work under live traffic conditions. Not only does this speed up the construction process, but it is safer for workers as well.

Local traffic traveling north or south on CO 257 will have to detour using Crossroads Blvd.,7th St., 1st St., and Garden Dr. to retain business accessibility. Trucks and commercial vehicles will have to detour using Eastman Park Dr. and County Rd. 23. Garden Dr. will remain open during the closure period, except for a couple of days in mid-July to allow CDOT to rebuild the Garden Dr. and CO 257 intersection. More information will be shared once it becomes available.

The Town of Windsor is responsible for work on the Eastman Park Dr./CO 257 intersection.

The Eastman Park Dr. & Hwy. 257 intersection improvement project is underway. The project completed environmental clearance surveying for possible wildlife impacts in mid-May and encountered minor delays due to weather. Last week, (Thursday, May 18) contractors were out drilling foundation holes for temporary traffic signal pole installation. Once the signals are installed and operational and the shoofly construction is complete, the temporary road detour will go into effect. Cones will be set up while work is completed along the shoulder of the road. In early June, the section of Eastman Park Dr. crossing Hwy. 257 will close for the summer while roadway work commences and the railroad completes track and signal improvements. Commuters using Eastman Park Dr. will have to detour to Garden Dr. using 1st St. or Cornerstone Dr. Highway 257 will remain open to traffic during the town’s intersection work.

Additionally, during that summer closure the Poudre Express stops along Eastman Park Dr. will be temporarily closed and relocated to the west. The eastbound stop will be relocated to the west side of the roundabout and the westbound stop will be relocated to Cornerstone Dr. north of the church parking lot entrance. Temporary pickup locations will be setup June 2 through June 5 and service moved to the new temporary pickup locations. Bus service will be maintained throughout construction.
