102-494 State highway plans, 1925-1933
After 1900, Washington counties worked increasingly with the state Highway Department to maintain roads built with state monies. The Highway Department sent reference copies of its highway plans to the counties. These plans are for State Highway #1 (Pacific Highway, through Auburn, Kent, Des Moines, Seattle, and via the North Trunk Highway to the Snohomish County line) and State Highway #2 (Sunset Highway, over Snoqualmie Pass). Volume 1 is for grading both highways, and there is one volume each per highway for concrete paving . In addition to construction details, the plans provide information about the land to either side of the right-of-way: property owners' names, location of structures such as barns and sheds, wetlands, pastures, cultivated fields, etc. The brittle blueprint pages have been reinforced with pasted paper. Maps on each page have been indexed by section-township-range.
