History

Template:This section needs expansion

1910s: Initial creation

Capitol Highway was initially conceived as a major thoroughfare and component of the Pacific Highway in the early 20th century. In March 1912, the first mile and a half of the Capitol Highway from Salem had been constructed by forty-eight convicts, supervised by George F. Rogers, chairman of the Capitol Highway Commission. Thirty of the convicts secured rock from a quarry south of Salem, and the other eighteen convicts constructed the roadway on top of a gravel foundation in three courses: tough rock on the bottom, then a course of finer stone, and on the top a course of screenings, rolled and hard-packed. The labor and material cost was 60 cents a yard.

Capitol Highway was originally opened on October 22, 1916, as a main thoroughfare between Portland and the Oregon State Capitol in Salem. It followed the route of Taylor’s Ferry Road, from the present-day Capitol Hill branch of the Multnomah County Library to the Tualatin River in Portland.

2020s: Improvements

In 2023, the Southwest Capitol Highway Improvement Project was completed in which a section of Capitol Highway was improved with new multimodal infrastructure such as bike lanes and sidewalks. The project cost a total of $27.5 million.

Bus service

Capitol Highway is served in part by TriMet bus lines 1-Vermont, 39-Arnold Creek/Hillsdale, 43-Taylors Ferry/Marquam Hill, 44-Capitol Highway/Mocks Crest and 45-Garden Home.
