Tilikum Crossing, Bridge of the People is a cable-stayed bridge across the Willamette River in Portland, Oregon, United States. It was designed by TriMet, the Portland metropolitan area's regional transit authority, for its MAX Orange Line light rail passenger trains. The bridge also serves city buses and the Portland Streetcar, as well as bicycles, pedestrians, and emergency vehicles. Private cars and trucks are not permitted on the bridge. It is the first major bridge in the U.S. that was designed to allow access to transit vehicles, cyclists and pedestrians but not cars.〔 Construction was begun in 2011, and the bridge was officially opened on September 12, 2015. In homage to Native American civilizations, the bridge was named with the local Chinook word for ''people''. At the time of its completion, the Tilikum Crossing was the first new bridge to be opened across the Willamette River in the Portland metropolitan area since 1973.〔 ==Route and function== Tilikum Crossing has its western terminus in the city's South Waterfront area, and stretches across the river to the Central Eastside district. In the 21st century, these two industrial zones have been evolving into mixed residential and commercial neighborhoods, and new transit accommodations are required by the growing populations. Both districts, however, are limited by antiquated road infrastructure that was deemed incapable of handling the increased traffic that could be expected from a conventional automobile bridge.〔 The primary rationale for the bridge was thus "first and foremost as a conduit for a light-rail line."〔 The bridge is south of, and approximately parallel to, the Marquam Bridge. The west "landing" is mid-way between the Marquam and Ross Island Bridges, and the east landing is just north of Southeast Caruthers Street, with the east approach viaduct reaching the surface at the west end of Sherman Street,〔 which the tracks follow to a new Oregon Museum of Science and Industry (OMSI) MAX station located near an existing Portland Streetcar station and the Oregon Rail Heritage Center. Although the planned MAX Orange Line was the impetus for construction of the bridge, the structure also carries TriMet buses, the Portland Streetcar Loop Service and emergency vehicles, and is open for public use by bicyclists and pedestrians. Use by private motor vehicles (except emergency vehicles) is not permitted.〔 Rerouting of TriMet bus routes onto the new bridge from more-congested crossings will shorten the travel time for riders on those routes. There are bike and pedestrian paths on both sides of the bridge and are wide.〔 The bridge connects a MAX station at OMSI on the east side of the river with a new OHSU/South Waterfront Campus MAX station on the west side.〔 OHSU is the city's largest employer, while OMSI is one of the city's largest tourist and educational venues, and the new bridge facilitates the connection of both to the regional MAX light rail system. The Orange Line continues south from OMSI to Milwaukie and northern Oak Grove and north from South Waterfront into downtown Portland. Two bus lines are scheduled be moved to the new bridge from the Ross Island Bridge on September 13, 2015: Lines 9-Powell and 17-Holgate/Broadway. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tilikum Crossing」の詳細全文を読む スポンサード リンク
