Interstate 705 is a short freeway spur connecting I-5 and Washington Route 7 with Downtown Tacoma. The WSDOT Interchange Viewer Diagram lists the route at 1.50 miles in length, with an official end at the 9th Street southbound on-ramp across from where Schuster Parkway begins northbound. Interchanges are unnumbered, but there are mileage markers for milepost 1.
SR 7 extends south from I-5/705 along a freeway to a partial interchange with E 38th Street. There were plans to extend the freeway south of E 38th Street, but such plans apparently lie dormant. The state route begins at U.S. 12 in Morton, winding its way northward near Storm King Mountain before descending upon Spanaway, Parkland and ultimately Tacoma.

The north end of the freeway, from a point one block south of the Murry Morgan Bridge (11th Street) to the beginning of Schuster Parkway, was constructed by the city of Tacoma. The state eventually took over a portion of this route, with the northern section remaining under city of Tacoma maintenance.1
Interstate 705 opened to traffic in 1991.2 Establishment of Interstate was conditionally approved by AASHTO on June 29, 1978.
