The Toads Parkway in the suburb Orchards.

State Route 500 begins at a junction with Interstate 5 in northern Vancouver and runs east with 2×2 lanes. There are two intersections halfway through the route through Vancouver, the rest is grade separated. In northeast Vancouver, a cloverleaf trail follows Interstate 205, the Portland region’s eastern bypass. The highway ends a few miles later in Orchard. The route then curves southeast through Orchard to Camas.


The road was created in 1937 as an alternate route of the then Primary State Highway 8, which ran east-west along the Columbia River. Secondary State Highway 8A ran parallel to this, further north in the city of Vancouver. The section east of Vancouver was created in the 1920s when a series of agricultural secondary roads were built. During the renumbering of the state routes in 1964, this road was numbered State Route 500.

The highway in Vancouver was created by making an existing urban arterial grade-separated. In 1990 only the cloverleaf with I-205 and a connection to I-5 in Vancouver existed. In the second half of the 1990s the connection with Andresen Road was made grade separated, followed by the section eastwards to I-205 around 2003. The connection with Gher Road opened around 2005 to the east of I-205. In 2013, the connection with St. Johns Boulevard opened.

Traffic intensities

Every day, 44,000 to 67,000 vehicles drive the section between I-5 and I-205 and 50,000 vehicles on the eastern section to the end of the highway in Orchard.

In both towns the road is partly a freeway, but outside it is an insignificant main road. The route is 57 kilometers long.

Travel directions

The 21st Street Bridge in Tacoma.

The road begins with a SPUI connection to Interstate 705 in downtown Tacoma. A wide cable-stayed bridge leads directly over the harbor of Tacoma, and the road is a grade separated expressway. The road here parallels Interstate 5, serving the Tacoma dockland area. At Taylor Way, the freeway section ends, before winding through the suburbs of Federal Way and Des Moines. In the suburb of Burien, at the Seattle-Tacoma (SeaTac) International Airport, the highway portion resumes, and the 2×2 lane road runs past the airport. One intersects at downtown Burien with SR-518, a short east-west highway to Interstate 5. After this one enters the city of Seattle and the highway is one of three north-south highways in the south of the city. The road ends at the large industrial valley south of downtown on SR-99, which continues straight into downtown as a freeway.


State Route 509 follows a historic wagon road from the 1890s. In 1923 this road became part of State Route 1. Originally the road went through the Murray Morgan Bridge, a vertical lift bridge from 1911. When the state routes were renumbered in In 1964 the road was numbered State Route 509.

The highway between Burien and Seattle was opened in 1968, after which State Route 509 was routed over it. There were plans to extend the highway further south to WA-516 in Des Moines. For this purpose, a more than 6 kilometers long route was purchased in the 1970s, which is still free of buildings today. However, the highway has not yet been built. In 1997, the short highway through the Port of Tacoma opened, including the landmark East 21st Street Bridge.


There are plans to convert SR-509 south of the Seattle – Tacoma International Airport to relieve Interstate 5. Construction of the first part started on October 16, 2020. The entire project should be completed by mid-2028.

Traffic intensities

In Tacoma, the road is not that busy, with 28,000 vehicles per day. The section through Federal Way, with 3,000 to 5,000 vehicles, is much quieter and not of major importance. Seattle has slightly more vehicles, namely 59,000 units.

At Puyallup, the highway turns north, joining SR-167, which continues toward Auburn and Kent.


The original connection is what is now 112th Street, which was created in the 1910s from agricultural roads. This was later numbered as the Secondary State Highway 5G. With the renumbering of 1964, this road was given the number State Route 512, whereby it was mainly planned as an all-new highway parallel to 112th Street. In the late 1960s, the western portion of the highway was constructed between I-5 in Lakewood and Vickery Avenue west of Puyallup. In the early 1970s, the highway was built to Puyallup, which was completed in 1972.
