Portland’s Freeway Names, Pacific Highway
Pacific Highway (99W, and surface streets):
While essentially a “Dead” highway, Portland’s highway system starts with the Pacific Highway. The Pacific Highway was completed in 1923, as the first “border to border” paved highway west of the Mississippi, it ran 341 miles from California to Washington. Eventually it was expanded from Canada to Mexico. This new road spurred a lot of development throughout Oregon. Several smaller cities moved their downtown core to be along the highway, and businesses sprung up along it’s full length to service travelers.
As 99W, Pacific Highway ran through Downtown Portland, crossed Willamette River via the Steel Bridge, and then continued up Interstate Avenue. In the 1950’s, the downtown portion was routed on the west side of the Willamette along Harbor Boulevard. But when Harbor was removed after the Freeway Protests, in 1974, it ran along First Avenue/Naito Parkway to the Steel Bridge.
Remains of the Pacific Highway still run parallel to I-5, along SW Barbur Boulevard.
