Changes are coming to TriMet bus lines serving the Lake Oswego area. While one bus line will see an added trip, two other lines will have low-ridership trips eliminated.

 Beginning Sept. 4, a weekday trip will be added to Line 35-Macadam/Greeley to help reduce overcrowding. Line 36-South Shore will have some trips changes. A trip from downtown Portland will be added at 6:10 p.m., while the 6:15 a.m. and 6:45 a.m. trips from Lake Oswego Transit Center and the 5:52 a.m., 6:20 a.m. and 6 p.m. trips from Tualatin Park & Ride will be discontinued. On Line 37-Lake Grove, two evening trips will be eliminated: the 5:54 p.m. trip from Lake Oswego Transit Center and the 5:37 p.m. trip from Tualatin Park & Ride.

TriMet decided on the service changes during its fiscal year 2013 budget process. The agency faced a $12 million shortfall stemming from the slow economic recovery, potential cuts in federal operating funds and union contract issues. The changes above are among those affecting 31 bus lines. Learn more at trimet.org/servicechange.

 Also, effective Saturday, Sept. 1, TriMet is raising most fares and eliminating all fare zones, including the Free Rail Zone. This change means a valid fare will be required to ride MAX Light Rail in downtown Portland and the Lloyd District.

TriMet is also moving to a simpler fare system with riders in each category choosing either a two-hour ticket or a day pass. Learn more at trimet.org/farechange.
