Talk:Primary State Highway 1 (Washington)

Route Length
The PSH 1 infobox shows a length of 796 miles (1,281 km). Where was that length found? How does the length of PSH 1 branches factor into the length of PSH 1? PSH 1 generally follows the same route as I-5 in Washington. The Interstate 5 in Washington infobox dsiplays a lenth of 276 miles. Sehome Bay (talk) 22:40, 16 July 2008 (UTC)

History notes
1937 law: "A primary state highway to be known as Primary State Highway No. 1, or the Pacific Highway, is hereby established according to description as follows: Beginning at the international boundary line in the vicinity of Blaine in Whatcom county, thence in a southerly direction by the most feasible route by way of Bellingham, thence to the east of Lake Samish, thence in a southerly direction by the most feasible route by way of Mt. Vernon, Everett, Seattle, Tacoma, Olympia, Centralia, Chehalis, Kelso and Vancouver to the Washington-Oregon boundary line on the interstate bridge over the Columbia river; also beginning at Bellingham on Primary State Highway No. 1, as herein described, thence in an easterly direction by the most feasible route to a point in the vicinity of Austin Pass in Whatcom county; also beginning at Bellingham on Primary State Highway No. 1, as herein described, thence in a southerly direction by the most feasible route by way of Blanchard to a junction with Primary State Highway No. 1, as herein described, in the vicinity of Mt. Vernon; also beginning at Mt.
