The following year, the Portland City Council separately approved the addition of a busway component to the I-205 Freeway, which was under construction at the time in Portland's east side; this bus corridor, which would be called the I-205 Transitway, ran physically separate from but parallel to the freeway. The I-205 Transitway's realization led TriMet to prioritize the development of the Banfield Transitway, a similarly planned stretch of I-84 connecting I-5 in downtown Portland east to I-205. The Banfield Transitway Project, which was originally proposed as another busway, was allocated the transfer funds although ultimately built as a light rail line. The first segment of the Metropolitan Area Express (MAX) began operating between Gresham and Portland on September 5, 1986.
