 Citizens of both Everett and Marysville proposed that a road between the two cities via the Snohomish River delta was needed, but the proposed roadway was rejected.A subsequent map published in 1911 showed the Everett and Marysville segments complete, but the bridges over the Snohomish River delta were railroad bridges.In 1913, the Pacific Highway was added to the state highway system and used Broadway (former SR 529) in Everett and State Avenue in Marysville to travel between Seattle and the Canada–US border.
