The repairs include crack sealing, concrete panel replacement and targeted pavement repairs. This work helps extend the useful life of each highway and provides a smoother ride for travelers, according to a news release from WSDOT.

Pavement repairs will begin at 8 p.m., Monday, July 14 in Whatcom County and move south towards King County. Information will be shared as work schedules are finalized. Rain may cancel or delay work schedules.
