Ross Dam Trail Head parking lot to be closed for paving beginning June 8

Beginning Wednesday, June 8 contractor crews working on behalf of the Washington State Department of Transportation will close the Ross Dam Trial Head parking lot on State Route 20 in anticipation of paving the week of June 13. 

All vehicles need to vacate the parking lot by 5 a.m. on June 13, or risk being towed at the owner's expense. The contractor requires full access to the parking lot to expedite the work and allow for it to be reopened as soon as possible. The parking lot is expected to be closed for approximately one week, weather permitting. If the weather is cool and rainy the closure time may be extended. 

Paving the Ross Dam Trail Head parking lot kicks off the SR 20 Rocky Creek to Granite Creek paving project, between milepost 102 at Rocky Creek in Rockport and Granite Creek at milepost 148, about 45 miles west of Winthrop. The preservation project allows crews to overlay the roadway with an aggregate surface treatment, between known as chip seal, that preserves the life of existing roadway. The work is expected to take most of the summer to complete and is similarly weather dependent. 

More information about construction and maintenance on SR 20 happening this summer is available at the SR 20 North Cascades Highway online open house. Real-time traffic information is available on mobile phones wit the WSDOT traffic app and by following WSDOT_north on Twitter.

        We acknowledge that Whatcom County is located on the unceded territory of the Coast Salish Peoples. They cared for the lands that included what we’d call the Puget Sound region, Vancouver Island and British Columbia since time immemorial. This gives us the great obligation and opportunity to learn how to care for our surrounding areas and all the natural and human resources we require to live. We express our deepest respect and gratitude for our indigenous neighbors, the Lummi Nation and Nooksack Tribe, for their enduring care and protection of our shared lands and waterways.
