Medano Pass Primitive Road Repairs Will Bring Road Delays and Closures at Great Sand DunesPosted March 15, 2017
Mosca, CO – Great Sand Dunes will begin road repairs along a section of the Medano Pass Primitive Road this week. The Medano Pass Primitive Road is a rough, 22-mile road connecting Great Sand Dunes with the Wet Mountain Valley and Colorado State Highway 69. The road is currently closed, due to snow, past Castle Creek picnic area to the top of the mountain pass and will remain closed until further notice. The repair work will bring delays and additional closures to currently opened areas of the Medano Pass Primitive Road. Specifically sections from Horse Trailer Parking area to Castle Creek picnic area will be impacted over the next 30 days.
Crews will remove failing road stabilization materials and replace the road sub-grade with imported gravel to prevent 4wd vehicles from bogging down in extremely deep soft sand sections of road. To preserve the primitive character of the road, the final project will result in a sand road surface with a stabilized base course. Once completed, the Medano Pass Primitive Road will still require 4WD vehicles to drive beyond the Point of No Return. Great Sand Dunes sees this repair project as an opportunity to improve the experience for 4WD enthusiasts.
Medano Pass Primitive Road will remain open from Horse Trailer Parking area to Point of No Return parking area, a 1.1 mile stretch of the road that allows 2WD and 4WD vehicular traffic. The Point of No Return parking area to Sand Pit parking area, a 0.7-mile stretch of the road that allows 4WD traffic, will be briefly closed to the public to complete repairs and allow access for large machinery to enter and exit the construction area. Visitors should yield to construction crews and machinery, leaving room for construction traffic to pass during the construction project.
The biggest closure that will impact visitors is the closure of the road between Sand Pit parking area and Castle Creek picnic areas. No traffic can pass between these points during construction even after hours. Road crews and directional and safety signage will be present before visitors approach the closure area. In addition, supplies and equipment will be staged at Horse Trailer Parking area, allowing for slightly reduced parking for visitors.
