The future Green Line was studied as two separate segments: the Northwest Corridor (from present-day North Carrollton/Frankford to Victory)[4] and the Southeast Corridor (from present-day Deep Ellum to Buckner).[5] When the Southeast Corridor was originally proposed, two options were considered for the final segment past Lake June Transit Center. One option would utilize an existing Southern Pacific rail corridor paralleling US 175, while the other would create a new corridor along Lake June Road stretching into the Pleasant Grove neighborhood. Both proposals terminated at Buckner Boulevard. The first proposal was ultimately chosen due to higher costs and neighborhood opposition associated with the second.[6] -Construction- On February 9, 2007, a trench collapsed during construction on the line killing one construction worker.[7] On March 12, 2007, the City of Dallas officials and DART made an agreement to make Burbank Station (formerly Love Field Station) a surface-level facility after a long debate of whether or not to make it an underground station.[8] Effective June 17, 2007, the Live Oak exit on (U.S. Route 75) was closed until 2009, as part of the Green Line Rail construction around the Bryan/Hawkins intersection. Two bridges in that area were removed and roads were lowered to street level.[9] On June 8, 2009, full-speed tests of the Green Line were conducted successfully with local officials and members of the media aboard.[10] The route of the test included the four stations, then still under construction, that joined the DART light rail system in September 2009. -Opening- The Green Line began operation on September 14, 2009, with a route from downtown Dallas southeast to Fair Park; this short route was scheduled to open in time to service the 2009 State Fair of Texas. On December 6, 2010 the line extended further to Pleasant Grove, as well as continuing northwest from Victory Station to Farmers Branch and Carrollton; both extensions, completing the Green Line.[11] Future plans edit The D2 Subway is planned to be implemented in 2028 and will reroute the Green Line's western terminus over the former Blue Line's tracks to terminate at UNT Dallas Station.
