The Minneapolis Streetcar System is a proposed streetcar system for the city of Minneapolis, Minnesota. Extensive studies and plans for the new system were completed in 2007 and presented to the Minneapolis City Council in January 2008;〔(【引用サイトリンク】author=Minneapolis City Council )〕 on April 2, 2010, the Council voted to approve the plans and seek funding.〔(【引用サイトリンク】url=http://www.ci.minneapolis.mn.us/council/2010-meetings/20100402/Council20100402Agenda.asp )〕 On December 21, 2010 the Federal Transit Administration granted $900,000 to further study the Nicollet and Central Avenue corridors.〔(【引用サイトリンク】url=http://www.fta.dot.gov/news/news_events_12233.html )〕 ==Streetcar vs Light rail== Based on similar federal funded streetcar programs in the USA (mainly Portland, Oregon) streetcars are rarely separated from other traffic and are not given traffic-signal priority over other vehicles (like Light rail), except in a few situations to allow the rail cars—which cannot turn as sharply as most other motor vehicles—to make some turns. In Portland, using this "mixed traffic" operation has reduced the cost of constructing each segment and—by not closing traffic lanes permanently to other traffic, as is typically done with light rail—also minimized disruption to traffic flow, and allows curbside parking to be retained, but also means slower operating speeds compared to light rail. Additional factors making the Portland Streetcar line less expensive to build per mile than light rail are that use of city streets largely eliminated the need to acquire private property for portions of the right-of-way, as has been necessary for the region's light rail lines, and that the vehicles' smaller size and therefore lighter weight has enabled the use of a "shallower track slab". The latter means that construction of the trackway necessitated excavating to a depth of only instead of the conventional (for light rail) depth of around , significantly reducing the extent to which previously existing underground utilities had to be relocated to accommodate the trackway.
