1960s • 1969 Tri-Met takes over for the nearly bankrupt
Rose City Transit Company. The system has 175 buses and a daily ridership of about 65,000.
1970s • 1970 Tri-Met takes over the
"Blue Bus" companies, the four companies which had been providing bus service to and within Portland's suburbs, The zone-based fare system was discontinued at that time, and remained in use until 2012. • 1977/78 The 22-block
Portland Transit Mall opens on downtown's Fifth and Sixth Avenues. The mall includes bus-only lanes and provides a hub to make it easier for riders to make connections. Tri-Met also introduces the seven "sector symbols", for different areas of the transit district, used at stops on the new mall: Brown Beaver (SE), Green Leaf (S), Yellow Rose (SW), Orange Deer (W), Red Fish (N), Purple Raindrops (NE) and Blue Snowflake (E) • 1978 After 3½ years using a
"flat" fare system, a zonal fare structure is reinstated, with three fare zones. The buses were manufactured by
Crown-Ikarus, a now-defunct partnership between
Ikarus, of Hungary, and
Crown Coach, of California, but they proved to be sufficiently trouble-plagued that the agency later sues the manufacturer to recover expenses tied to excessive repairs; a settlement was reached in 1987. The last bus was retired in 1999 and TriMet did not purchase articulated buses again until 2019 (for the Division Transit Project, to enter service in 2022). • 1982 In September, Tri-Met introduces a
proof-of-payment (or "self-service") fare system for all service, but discontinues it in June 1984, due to fare evasion, high equipment repair costs and other problems. • 1983 Completion of the installation of
two-way radios on the entire fleet; 100 buses already had radios by 1980, and all others were equipped in 1982–83. • 1986 As part of a package of budget cuts, Tri-Met discontinues its all-night
"Owl" service, making Portland the second largest U.S. city without all-night transit service. Seven regular (daytime) bus routes also were eliminated. , an example of which is the 1992
Flxible Metro shown in this 2013 photo.
1990s • 1992 The first bike racks are installed on the fronts of some Tri-Met buses, as part of a one-year trial project. • 1997 The first
low-floor buses and light-rail cars go into service. • 1998 Westside MAX (now known as the Blue Line between Portland and
Hillsboro) opens. Tri-Met also establishes bus lines that come every 15 minutes or sooner everyday, lessening the need to consult a schedule when using them. • 1999
Satellite-assisted bus arrival time displays (later to be named
Transit Tracker) are installed at select major bus stops in North Portland and downtown.
2000s • 2001 Fareless Square is expanded to a small portion of Northeast Portland between
Lloyd Center and the
Steel Bridge. Airport MAX (the
Red Line) begins service on September 10 after a public/private partnership, prompted by a proposal from
Bechtel Corporation, enables its construction years ahead of TriMet's plans for the use of public funds. Bechtel received exclusive development rights to 120 acres (486,000 m2) near the entrance to
Portland International Airport. The original MAX line began to be referred to as the MAX Blue Line upon the opening of the Red Line. Bus sector symbols began to be phased out from maps and publications. • 2002 With the September schedule change, Tri-Met launches a new
corporate identity strategy. It is renamed
TriMet (without a hyphen) and a new
logo and blue, white and yellow livery are introduced. • 2007 The
Portland Mall, on 5th and 6th Avenues, is shut down for rebuilding and southward extension (to
PSU), including adding a second light-rail alignment through downtown. The rebuilding, to take over 2 years, is part of the
MAX Green Line project, but will also replace all infrastructure for buses on the already 29-year-old transit mall. Most bus routes serving downtown are detoured to other streets until 2009. • 2009 The
WES Commuter Rail opens on February 2. WES (Westside Express Service) provides service between Beaverton and Wilsonville with stations in Tigard and Tualatin in between. • 2009 Due to the
Great Recession's effect on the agency's finances, the board approves a series of service reductions, to take effect in September. The board votes on August 12 to discontinue
Fareless Square for bus service beginning in January 2010, while retaining
fare-free rides in the downtown area on MAX and the Portland Streetcar. • 2009 On August 30, MAX service on the transit mall is introduced, with the shifting of the Yellow Line to the new alignment. September 12 brings the opening of the
Green Line, also using the new transit-mall tracks, running from downtown (PSU) to
Clackamas Town Center. It is TriMet's first light rail line serving Clackamas County. , built as part of the
MAX Orange Line project, opened in 2015.
2010s • 2012 TriMet purchases 55 new Gillig diesel buses to begin replacing buses dating back to 1990. The last four of the new buses are
hybrid-electrics estimated to be 20-50% more fuel-efficient and produce 95% fewer emissions; they replaced hybrid buses that were in service since 2002. • 2012 TriMet discontinues "Free Rail Zone" (formerly known as the "Fareless Square") in Downtown Portland and ends use of three-zone, distance-based fare system. Until this time, the TriMet district was divided into three fare zones, with fares based on the number of zones in which a passenger traveled. • 2015 TriMet opens the new
MAX Orange Line from Downtown Portland to
Milwaukie, and the
Tilikum Crossing, used by the Orange Line and two bus lines • 2018 After 32 years without any all-night transit service, TriMet extends service hours on lines 20-Burnside/Stark and 57-TV Highway to run 24 hours a day. The agency also establishes Line 272-PDX Night Bus to provide early-morning service between NE 82nd Avenue and the
Portland International Airport. (This service was discontinued April 5, 2020 due to the COVID-19 pandemic and has not returned.) • 2019 TriMet introduces a new paint scheme,
2020s • 2022 on September 18, TriMet's 14-mile
Frequent Express line opens. 31 60-foot
Novabus LFSA buses are put into service for use on the line. • 2024 on August 25, TriMet completed the
A Better Red project. == Future ==
