COTTONWOOD ROAD CLOSURE
Cottonwood Road reconstruction project underway to improve safety and timber hauling capacity
Closure expected from June 8 through 19th, and delays expected through July
Durango, CO., May 27, 2026 — The San Juan National Forest has begun reconstruction of National Forest System Road (NFSR) 532, also known as Cottonwood Road. This project will continue through July, 2026, and temporary closures and delays will be required during reconstruction. Cottonwood Road is located north of the town of Dolores, Colo. on the Dolores Ranger District. The project will improve safety and access along the route, as well as making it more viable for timber hauling.
A full road closure will be required for the replacement of the Mavreeso Creek bridge, which will take place between June 8 and June 19 (see closure order and map). This closure will only impact a small segment of the Cottonwood Road between milepost 3.7 to and 4.6. The closure will prevent users from traveling from the Dolores Norwood road to the West Dolores road and visa versa. There will be no through traffic.
Why This Project Is Needed
The reconstruction addresses safety concerns related to narrow road sections, limited sight distance, and the weight-restricted bridge over Mavreeso Creek. These improvements will also support future active forest management and timber removal.
What’s Planned
Install new culverts and extend existing ones to accommodate a wider roadway
Remove roadside vegetation to improve visibility
Replace the one-lane, weight-restricted Mavreeso Creek bridge with a large culvert
Resurface the entire 7.5-mile stretch of road
When complete, Cottonwood Road will provide an alternate timber haul route for existing timber sales and related work on the Dolores Ranger District, reducing the need to transport timber through the town of Dolores. The road work is being completed in partnership with the National Wild Turkey Federation.
