Saint Paul, Walsh Construction served as the general contractor. In July 2011, the Metropolitan Council officially named the Central Corridor as the Green Line. As of August 2013, construction was completed and test trains began running over the line which opened to the public on June 14, 2014. An interesting component of the Green Line project was the complexities in design layout. Land surveyors worked directly with over twelve subcontractors to complete the work. A particular area required exclusive attention and support, that being outside the University of Minnesota's biology department. Between Pleasant and Harvard streets there was 1/8" of tolerance between design and as-builds. Control factors used in the biology labs would be impacted by the electromagnetic radiation emitted from the nearby light rail. The 1/8" tolerance is said to cancel out any EMR that the light rail may produce. Additional stations Some in favor of the line have expressed concern with the number of stations. The neighborhoods along University have demanded that the line have stations every half-mile, from Snelling to Rice Street, which would mean stations at Hamline Avenue, Victoria Street and Western Avenue. In February 2008, the Central Corridor Management Committee passed a resolution to include below-ground infrastructure for the Hamline, Victoria and Western stations "with the understanding that, if the CEI increases or other dollars are made available by mid-summer 2008, the first claim on those dollars would be one of the infill stations." The Metropolitan Council has included this infrastructure work in their Draft Environmental Impact Statement and has also committed to building one station if any funds become available. As of 2009, the Federal Transit Administration has increased the Cost Effectiveness Index such that buildout of one station is now feasible. On January 25, 2010, the FTA announced that the three "infill" stations will be built. Upon opening, all five stations between Snelling and Rice Street were built - Hamline Ave, Lexington Pkwy, Victoria St, Dale St, and Western Ave. Route Opposition Many businesses along the line were opposed to its development because of reduced access for automobiles. Under the final plans, 87% of on-street parking disappeared along University Avenue between Raymond Avenue and Rice Street. At least one restaurant has cited light rail construction as a reason for closing. The corridor contains working-class residents and immigrant populations from Laos and Vietnam.
