Lane 6 North Construction

**UPDATED** - Summer Route Closure of Lane 6 N between Mosca and Great Sand Dunes NPP begins June 6, 2022

The project will impact traffic on Lane 6 between CO Hwy 17 and CO Hwy 150 and eliminate through access beginning June 6 and continuing to September 1, 2022. The project is divided into East and West sections and each section will experience full closure of both lanes 24 hours per day as noted below. During this period, visitors to the Great Sand Dunes National Park and Preserve should avoid Lane 6 and instead detour south to US Hwy 160. 

Partial route access will only be as far as the San Luis Lakes State Wildlife Area (an 8-mile stretch of the road) for travelers accessing the SWA and only accessible for local access. Local access is defined as local private property owners living along Lane 6 and federal property owners (areas not publicly accessible, administrative use only). All users (travelers and local access) accessing any portions of Lane 6 should expect delays up to 30 minutes.
