A-42 With the opening of a new light rail line, the Tri-County Metropolitan Transportation District of Oregon (TriMet) typically makes adjustments to the surrounding bus network to optimize ridership and service efficiency. Adjustments to local bus service assumed for the purpose of the analysis in this Draft EIS are described below. TriMet would make final decisions on bus service and routing changes for the Southwest Corridor Light Rail Project shortly before the opening of service. Two lines operating on SW Barbur Boulevard in the No-Build, the line 12 from Tigard to downtown Portland and the line 94 express from Sherwood to downtown Portland, would be removed. The line 93 from Sherwood to Tigard would be extended to the Barbur Transit Center with service added to maintain frequency lost with the line 94 removal. The line 44 from downtown Portland would be shortened to terminate at PCC-Sylvania, removing its No-Build routing between the campus and Bridgeport Village along SW Kerr Parkway and SW Boones Ferry Road. Instead, the line 96, an express route between Wilsonville and downtown Portland in the No-Build, would be re-routed north of Bridgeport to travel along the roads from which the 44 would be removed. The line 96 would serve PCC-Sylvania and continue along SW Capitol Highway to terminate at the Barbur Transit Center. With light rail serving the Marquam Hill connection, lines 64 and 65 to Marquam Hill, from Tigard and Burlingame, respectively, would be removed. Line 8, serving between NE Portland and Marquam Hill, would have peak service reduce by three vehicles per hour because its loads would be reduced by light rail service. Lines 1 and 38 would be shortened to terminate at Burlingame near the Custer station instead of continuing into downtown Portland. The line 54 from Beaverton would utilize a shared transitway with the light rail between SW Capitol Highway and SW Lincoln Street, allowing it to avoid congestion and improve reliability. Figures A-1 and A-2 show the assumed transit network for the No-Build Alternative and light rail alternatives, respectively.

The maps illustrate the location of the alignment, stations and park and rides. Park and rides are labeled with their assumed maximum capacity. Along the alignment, the maps show whether the alignment would run in a roadway or separated from roads, and whether it would be at grade, structured, or in an underpass. At-grade intersections along the alignment are identified as signalized, gated or both. Additional protected walk/bike crossings away from stations or intersections are also labeled.
