Interstate 705

Interstate 705 (abbreviated I-705, also known as the Tacoma Spur) is a short Interstate Highway spur route of Interstate 5 located entirely within Tacoma, Pierce, Washington, United States. I-705 serves as the connector between Interstate 5, Downtown Tacoma, Tacoma's waterfront, North Tacoma, and the Tacoma Dome. I-705 was the last portion of the Interstate Highway System to be constructed in Washington.

Route description

The Tacoma Spur begins as a continuation of Washington State Route 7 (SR 7) underneath I-5 in Tacoma, and has a posted speed limit of 60 miles per hour (97 km/h) for the entire length (1.5 Miles).

Traveling northbound as a continuation of SR 7, the first exit is for South 26th Street, which provides access to the Tacoma Dome, the Tacoma Dome transit hub and the Tacoma Amtrak station. A single-point urban interchange (SPUI) with SR 509 (South 21st Street) provides access to the University of Washington Tacoma campus, as well as the Port of Tacoma via the East 21st Street Bridge. The left two lanes of I-705 separate, providing access to A Street, as well as South 15th Street / Pacific Avenue, however travelers merging onto northbound I-705 can not access this exit. The Bridge of Glass, linking the Museum of Glass on the shorefront to downtown Tacoma, passes over I-705 as it continues north, paralleling the Thea Foss Waterway to the east, and Firemans Park to the west. A signalled at-grade intersection with Stadium Way marks the end of I-705 northbound.
