The Springwater Corridor Trail is a bicycle and pedestrian rail trail in the Portland metropolitan area in Oregon, United States. It follows a former railway line of the same name from Boring through Gresham to Portland, where it ends south of the Eastbank Esplanade. Most of the trail, about long, is paved, though about overlaps city streets in Sellwood, and about near Boring has recently been paved. A large segment roughly follows the course of Johnson Creek, and crosses it on bridges many times. Much of the corridor was acquired by the City of Portland in 1990; remaining segments were acquired by Metro thereafter.〔(【引用サイトリンク】title= Springwater Corridor )〕 The trail is part of the Portland area's 40 Mile Loop trail system. It connects to many adjacent or nearby parks, including Tideman Johnson Natural Area, Powell Butte, and others. == History == The Springwater Division rail line was named for a planned connection to Springwater, Oregon. The Portland Traction Company operated rail service from Portland to Boring from 1903 until 1989. Passenger service peaked in 1906 and ended in 1958. Oaks Amusement Park—and five other city parks—were built to encourage weekend passenger traffic. Freight trains brought farm produce into Portland.〔(【引用サイトリンク】 Springwater Corridor, SE Ivon St to Boring, Oregon )〕 When the Oregon Department of Transportation (ODOT) began a project to widen Oregon Highway 99E, a new, expensive overpass was required for the rail line. Citing low traffic volumes, construction was refused and the line was put up for sale. This was of great interest to the 40-Mile Loop Trust, a conservation effort formed in 1981〔 to build a trail around Portland connecting its many parks, planned since 1904, but had made little progress. The Trust had proven effective at getting many key governmental agencies to work with each other. They called upon the Southern Pacific and Union Pacific railroads, co-owners of the abandoned line, to transfer the land to the Trust. This matter was subject of a battle between on-line railroad shippers and Metro. However, by 1990, the deal was completed, and represented a significant step in the completion of the Loop.〔 〕〔(【引用サイトリンク】 Foster Auto Parts v. City of Portland, 15 P.3d 573 (Or. App., 1998) )〕 During master planning in 1991 for conversion, the projected use of the corridor was 400,000 people annually, distributed as 56% bicycling, 36% walking, 9% jogging, and 3% equestrian. By 2003, usage was expected to exceed one million users per year. Prior to paving, much of the trail was suitable for mountain biking. Construction of the east–west segment of the trail between Oregon Highway 99E and Gresham was completed in 1996. An additional mile east of Gresham was built in 2000. In 2005, a north–south "Springwater on the Willamette" segment opened between central Portland and the Sellwood Bridge along the Willamette River.〔 Unlike the other sections of the trail, the rail line remained, separated by a fence. The line is currently operated by the Oregon Pacific Railroad. The last significant section of the trail was completed ahead of schedule in summer 2006, when the construction of three new bridges over Johnson Creek, Oregon Highway 99E and a railroad line, allowing users to cross them without having to detour and mix with traffic on busy streets. As of 2012, a one-mile gap in the Sellwood area remains, but there are plans to reduce it. This segment was one of the parks and trails recommended for funding by a Metro advisory panel in 2001. In 2003, Portland was one of 25 cities that received a $200,000 grant from Active Living by Design to promote urban planning that encourages physical activity. Some of the money was allocated to a Lents Station interpretive trailhead along the Springwater Corridor. In 2006, the City of Portland rejected a development proposal for a property that did not include an easement for a greenway along the Willamette River, and would have prevented completion of a planned connection between the Springwater Trail and the Eastbank Esplanade. The easement requirement was upheld by the Oregon Court of Appeals on February 13, 2008. In late 2013, paving was completed on a stretch from Rugg Road to Boring Station Trailhead Park. The vegetation removal for the project started in July 2013 and was completed on December 2, 2013. The paving project cost was $1.9 million.〔(【引用サイトリンク】title=Springwater Corridor Trail )〕 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「Springwater Corridor」の詳細全文を読む スポンサード リンク
