State Route 548 (SR 548) is a 13.85-mile-long (22.29 km) state highway serving Whatcom County in the U.S. state of Washington. The highway travels northwest between two interchanges with Interstate 5 (I-5) north of Ferndale and in Blaine. 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.
SR 548 begins north of Ferndale as Grandview Road at a diamond interchange with I-5, signed as exit 266, and travels west over California Creek into rural Whatcom County. The highway crosses a BNSF rail line and continues west towards Birch Bay, passing north of Lake Terrell and its state game refuge. SR 548 turns north onto Blaine Road at a roundabout and travels through Birch Bay before crossing Dakota Creek into Blaine. The highway crosses over the BNSF rail line and turns northwest onto Peace Portal Drive northwest of an interchange with I-5. Peace Portal Drive continues north along the rail line and Drayton Harbor into Downtown Blaine, ending at a dumbbell interchange with I-5, signed as exit 276, continuing east as D Street.
