State Route 28 (SR 28) is a 135.32-mile (217.78 km) long state highway serving Douglas, Grant, and Lincoln counties in the U.S. state of Washington. The highway begins at an intersection with U.S. Route 2 (US 2) and U.S. Route 97 (US 97) in East Wenatchee and travels east through Quincy, Ephrata, and Odessa before ending at US 2 in Davenport. The route parallels the Columbia River and a rail line operated by BNSF Railway through mostly rural areas.
SR 28 has been signed into law as the Sunset Highway and North Central Highway since 1915. These two highways later became State Road 7 and State Road 10, respectively, in a 1923 renumbering. The two roads kept their numeral designation past the 1937 renumbering, becoming Primary State Highway 7 (PSH 7) and Primary State Highway 10 (PSH 10), later joined in 1964 to form SR 28.
