Route description

SR 599 runs 1.75 miles (2.82 km) from I-5 north to SR 99, within the city of Tukwila. The route links I-5 with West Seattle, avoiding the West Seattle Bridge.[3][4][5] WSDOT has found that about 48,000 motorists utilize the road daily at the I-5 based on average annual daily traffic (AADT) data.[6][7][8]

History

SR 599 became a state highway in 1971,[1] but has been part of Washington's older highway system (Primary and Secondary Highways) from 1957 to 1970.[9] The highway, then known as PSH 1 WM, or West Marginal Branch,[9] was built during the 1960s. When it was completed, around 1968, U.S. Route 99 (US 99) was about to be removed from the system, so when I-5 was completed up to Tukwila, US 99 switched to the route of SR 599. Later on, the current route of SR 599 became known as US 99T (Temporary) and later SR 99T in 1964. In 1971, the highway became SR 599.[1]
