Transportation
Most streets in downtown Portland are one-way. Naito Parkway (two-way, formerly known as Front Avenue) is the farthest east, while most of the high-rises end by I-405 to the west. Interstate 5 runs on the opposite bank of the river, crossing over on the Marquam Bridge. U.S. Route 26 connects downtown Portland to the Oregon Coast and the Cascade Range.
Downtown is also served by several forms of public transportation. Because of its shorter blocks, walking is often preferred by the locals. TriMet, the regional mass transit agency, operates MAX light rail on two alignments in downtown, one running east/west on Yamhill and Morrison streets and north/south on 1st Avenue, the other running north/south on 5th and 6th avenues. On the latter two streets, an extensive transit mall—known as the Portland Mall—limits private vehicles and provides connections between more than fifty bus lines, MAX light rail, and the Portland Streetcar.
The southern part of downtown and the West End are also served by the Portland Streetcar system, operating from South Waterfront north into the Pearl and Northwest Portland districts. The system is currently a single route, measuring 3.9 miles (6.3 km) end to end, and connects in South Waterfront with the Tram (aerial cableway) to Oregon Health & Science University (OHSU).
Starting in 1975 and continuing for almost four decades, all transit service in downtown was free, as downtown was entirely within TriMet's Fareless Square, which also covered the nearby Lloyd District after 2001. However, in 2010, free rides became limited to MAX and streetcar service – no longer covering bus service – and the zone renamed the "Free Rail Zone", and in September 2012 the fareless zone was discontinued entirely, because of a $12 million shortfall in TriMet's annual budget.
