State Route 7 (SR 7) is a state highway in Lewis and Pierce counties, located in the U.S. state of Washington. The 58.60-mile (94.31 km) long roadway begins at U.S. Route 12 (US 12) in Morton and continues north to intersect several other state highways to Tacoma, where it ends at an interchange with Interstate 5 (I-5) and I-705. The road has several names, such as Second Street in Morton, the Mountain Highway in rural areas, Pacific Avenue in Spanaway, Parkland and Tacoma and 38th Street in Tacoma. Near the end of the highway there is a short freeway that has been proposed to be extended south parallel to an already existing railroad, owned by Tacoma Rail, which serves as the median of the short freeway.
The earliest road to use the current route of SR 7 first appeared in a 1900 map of the Tacoma area and has been part of the state highway system since 1909, when the Alder-Kosmos Road was added to the system as State Road 18. State Road 18 became part of two branches of State Road 5 in 1923 and later branches of Primary State Highway 5. During the 1964 highway renumbering, the branches became SR 7.
