Washington State Route 16

State Route 16 (SR 16) is a 27.16-mile-long (43.71 km) state highway in the U.S. state of Washington, connecting Pierce and Kitsap counties. The highway, signed as east–west, begins at an interchange with Interstate 5 (I-5) in Tacoma and travels through the city as a freeway towards the Tacoma Narrows. SR 16 crosses the narrows onto the Kitsap Peninsula on the partially tolled Tacoma Narrows Bridge and continues through Gig Harbor and Port Orchard before the freeway ends in Gorst. The designation ends at an intersection with SR 3 southwest of the beginning of its freeway through Bremerton and Poulsbo. SR 16 is designated as a Strategic Highway Network (STRAHNET) corridor within the National Highway System as the main thoroughfare connecting Tacoma to Naval Base Kitsap and a part of the Highways of Statewide Significance program.

SR 16 was created during the 1964 state highway renumbering as the successor to Primary State Highway 14 (PSH 14). PSH 14, which had itself been the successor to State Road 14, traveled northeast from Shelton to Gorst and south to Gig Harbor. PSH 14 was extended over the Tacoma Narrows in 1939 on the unfinished Tacoma Narrows Bridge, which would later collapse months after opening in 1940, into Tacoma over Secondary State Highway 14C (SSH 14C). SR 16 has been expanded into a freeway in stages beginning with the original Nalley Valley Viaduct in Tacoma in 1971, and ending with the opening of an interchange near Port Orchard in 2009. Later improvements to the corridor include the installation of high-occupancy vehicle lanes that connect to I-5 and the rest of the freeway network in Pierce County, which were completed in 2019.

Route description

The twinned Tacoma Narrows Bridge carries SR 16 between Tacoma and the Kitsap Peninsula

SR 16 begins as an elevated freeway at an interchange with I-5 in Tacoma southwest of downtown. The interchange includes direct ramps for a set of high-occupancy vehicle lanes (HOV lanes) and collector–distributor lanes as it travels over South Tacoma Way and a railroad that carries Sound Transit's Sounder commuter train. SR 16 intersects Sprague Avenue at an interchange and turns west, passing a golf course and Cheney Stadium. A parallel pedestrian and cycling path, the Scott Pierson Trail, runs along the north side of the freeway.<ref name="wsdot-spt">Template:Cite map</ref> At a partial interchange with Center Street near Fircrest, SR 16 turns northwest and travels around the Tacoma Community College campus to an interchange with North Pearl Street (SR 163), which provides access to Ruston and the Vashon Island ferry.<ref name="google">Template:Google maps</ref>

Every year, the Washington State Department of Transportation (WSDOT) conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of annual average daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2012, WSDOT calculated that the busiest section of SR 16 was west of its interchange with Union Avenue in downtown Tacoma, serving 112,000 vehicles, while the least busiest section is after the SR 160 interchange west of Port Orchard, serving 32,000 vehicles.<ref name="ATR">Staff (2012).
