light rail lines. These funds were used to finance the FrontLines 2015 expansion project, which added four TRAX extensions by 2015 (as well as an expansion to FrontRunner commuter rail). In order to support planned TRAX expansion, UTA ordered 77 Siemens S70 light rail vehicles from Siemens AG. It is the company's largest light rail contract in the United States to date. In 2008, construction began on two new extensions: one extension of through West Valley City (now part of the Green Line) and another extension of through the southwest portion of the Salt Lake Valley (now part of the Red Line). Both extensions were debuted in ceremonial openings on August 2, 2011, and permanently opened for regular service on August 7. Both extensions were completed ahead of schedule and under budget. Upon completion of these expansions UTA adopted a color-code line names in place of their old destination-based line names. After the first year of operation, ridership on these portions of the Green and Red lines was less than was projected by UTA. However, UTA has stated the projected ridership was for the year 2015. Since these lines were opened for service years earlier than originally planned, the anticipated growth on the west side of Salt Lake Valley has just not happened, yet. UTA affirms that by 2015 ridership will meet the original projections. A line from Salt Lake City International Airport to the University of Utah was in the original plans for the system to be completed before the 2002 Winter Olympics, but funding shortages only allowed the eastern portion to be constructed. The airport line eventually came to fruition, however, and ground was broken on October 22, 2008. The extension opened on April 14, 2013, adding and six additional stations to the Green Line, including a transfer station to the FrontRunner. On November 14, 2006, the Draper City Council approved the TRAX extension into that city. Neighbors in the area have continually fought the route suggested by UTA. The route follows an old rail line and UTA already owned the right of way. An alternative route that would run down the middle of State Street was also studied by UTA. Use of the UTA right of way for the line was challenged in court and later approved by the Utah Supreme Court on July 12, 2008. UTA published a draft Environmental Impact Statement for the new line
