An early wagon road along North Creek between Bothell and Lowell (now part of Everett) was built in the late 19th century by local settlers and the county government. The road was graded and improved with a permanent (but unpaved) surface in the early 1910s using funds allocated by the state government. It was incorporated into the state highway system in 1913 as part of the Pacific Highway, the primary cross-state route in Western Washington. The Bothell–Everett portion of the highway was paved with concrete in 1916, following a bond issue for improved roads approved by Snohomish County voters the year prior.
