WASHINGTON — Washingtonians hitting the road to visit some of the region’s most popular summer destinations should plan for a few extra delays this year as transportation crews begin resurfacing work on state highways around the Olympic Peninsula, Mount Rainier, and the coast.

According to the Washington State Department of Transportation, seasonal repairs are scheduled in Pierce, Mason, Jefferson, Clallam and Grays Harbor counties and are scheduled to continue until early fall. In a news release, WSDOT said resurfacing work requires dry and warm weather, and cannot be completed during the cooler, rainier season, which leaves only a short window each year.

That means drivers should expect lower speed limits, flaggers and alternating traffic at times on roads leading to places like Mount Rainier National Park, Ocean Shores, and Lake Cushman.

Here is where the work is planned this summer:

Clallam County

• 6 miles of SR 706 generally between SR 7 and Mount Rainier National Park (milepost 0.01 to 13.6)

Drivers can get a headstart on delays by checking the WSDOT app or social media feeds and reviewing their real-time travel maps.
