kept their numerical designations and became PSH 14 and PSH 21, respectively. PSH 21 was extended southwest from Bremerton on the former Navy Yard Highway to Gorst, while PSH 14 turned south at Gorst and headed towards Tacoma. A branch of PSH 14, named SSH 14A, was designated on a gravel road that connected the main highway at Belfair to US 101 in Shelton. In 1955, PSH 21 was extended southwest along PSH 14 from Gorst to Union, shortening PSH 14 to its current route as SR 16. During the 1964 highway renumbering, a new state route system replaced the existing primary and secondary state highways and SR 3 was designated along SSH 14A, PSH 14, and PSH 21 on its present route when it was codified in 1970. Construction of the freeway section of SR 3 began in 1963 between SR 304 in Navy Yard City and Silverdale west of Bremerton and was opened in February 1968 at a cost of $2.2 million. The freeway was extended north towards Poulsbo in late 1973, and further north to Naval Submarine Base Bangor in 1981 after the arrival of Ohio-class submarines at Bangor. The Poulsbo section was widened and extended through an interchange with SR 305 in the early 1990s. The freeway was originally intended to connect with SR 16 (itself upgraded to a freeway in the 1970s and 1980s) with a bridge across the Sinclair Inlet. In the 2000s, WSDOT re-built the interchange between SR 3 and SR 303 in Silverdale at a cost of $26 million, paid for by a 2003 gas tax. The new interchange, opened in November 2007, split the western terminus of SR 303 between two exits, signed as 45A and 45B, and removed a loop ramp that created turning conflicts. WSDOT began study of a Belfair bypass in 1966 and completed a provisional report in 2010 that did not recommend constructing a bypass of the community, instead opting for a project to widen the highway and add safety improvements that began work in late 2013. The project was revived later in the decade and is scheduled to be completed by 2026, carrying the new alignment of SR 3 while the existing road remains as a business route through Belfair.
