State Route 7 (SR 7) is a state highway in Lewis and Pierce counties, located in the U.S. state of Washington. The 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.
