State Route 548 (SR 548) is a state highway in Whatcom County, Washington, United States. It travels for 14 miles (23 km) between Ferndale and Blaine, terminating at interchanges with Interstate 5 (I-5) at both ends. SR 548 in Blaine, named Peace Portal Drive, follows the route of the Pacific Highway, later U.S. Route 99 (US 99) and Primary State Highway 1 (PSH 1). US 99 was decommissioned during the 1964 highway renumbering and the highway was maintained by Whatcom County until it was designated as SR 548 in 1991.
