Drivers traveling through Ferndale, WA should plan ahead before Tuesday, May 19: Seamount Drive between Vista Drive and Malloy will be completely closed to through traffic from 7 a.m. to 5 p.m. The City of Ferndale issued the notice Thursday, explaining the closure is tied to work on a private development project in the area.

Ferndale is one of the fastest-growing cities in Whatcom County, and road closures associated with new residential and commercial development have become a regular occurrence as the city expands its infrastructure. The Seamount Drive corridor sits in a mixed-use area of Ferndale near Vista Drive and the roundabout connecting several residential neighborhoods.

For the duration of the closure, signage will direct drivers to detour around the affected section via the Vista Drive roundabout. The roundabout is already a key intersection in that part of Ferndale, and the city anticipates detour routing will be clearly marked. Residents on either side of the work zone will maintain access to their homes throughout the day.

The closure is expected to last for one day only. If work is completed ahead of schedule or conditions change, Ferndale Public Works may reopen the road earlier, but drivers should plan for the full 7 a.m. to 5 p.m. window when scheduling Tuesday travel.

For drivers commuting to or from Ferndale on Tuesday, the Guide Meridian (SR 539) remains the primary north-south artery and is not affected by this closure. The Vista Drive roundabout detour will add minimal time for most trips. Drivers unfamiliar with the area should allow a few extra minutes and watch for detour signage.

Ferndale regularly posts traffic notices on its website. Residents can monitor cityofferndale.org for any updates to the Tuesday closure schedule or notice of future road work as development continues across the city.

For related road news in Whatcom County, Hannegan Road will also see single-lane delays from May 18 through 21 due to crack sealing operations by Whatcom County Public Works.

Both projects are part of the broader infrastructure activity typical of this time of year, when dry weather creates favorable conditions for paving and road maintenance across Whatcom County.
