[7] WSDOT has also designated SR 310 as a Highway of Statewide Significance, which is critical to connecting major communities in the state.

[11][12][13] SR 3 was created during the 1964 highway renumbering, following the route of PSH 21 from Shelton to Port Gamble, and traveled along Callow Avenue and Kitsap Way within Bremerton.

[14][15] Work began on a freeway bypass of Bremerton in the 1960s, with the first section opening in February 1968 and SR 3 being re-aligned onto it after 1970.

[16][17] After the Ohio-class submarines were commissioned by the United States Navy and Naval Base Kitsap was selected to house them in 1977, a $36.9 million investment in local highways was spent to expand the SR 3 freeway and build a bypass of Silverdale for SR 303.

[10] No major revisions to the route of SR 310 have occurred since it was established in 1991,[18] however the City of Bremerton rejected a proposal to repave Kitsap Way in 1997.
