In 1975, the Columbia Region Association of Governments (CRAG) proposed a series of "transitway" corridors in the Portland metropolitan area amid calls to transfer federal assistance funds from the canceled Mount Hood Freeway project to other transportation projects in the region. This proposal, which CRAG adopted in an interim transportation plan, envisioned buses serving these corridors, with the exception of a light rail corridor running from downtown Portland to Oregon City in Clackamas County with a spur line from Milwaukie to Lents, which would occupy the old Portland Traction Company rights-of-way. Indecision about the exact use of the transfer money, as requested by the Federal Highway Administration, led to a delay in acquiring the funds. That November, regional transit agency TriMet lost its option to purchase used PCC streetcars from Toronto, which it had hoped to use on the proposed Portland–Oregon City line, after the Toronto Transit Commission declined to renew TriMet's hold.
