17, 2008, after liquidating all of its assets, repaying its debts, and transferring its remaining $425,963.07 to the King County Metro system. The monorail project ultimately cost Seattle taxpayers $124.7 million. Design The plan, as proposed by CP-1 (2002) proposed five distinct corridors based on the Intermediate Capacity Transit Study and prioritized the Green Line, a north–south route on the west side of the city, as the first of the five to be built. The other four lines included two additional north–south routes, in the center (Blue) and east (Gold) sides of the city, and two east-west connectors, one just north of the Lake Washington Ship Canal (Purple) and the other near the southern city limits (Red). Two future extensions were proposed to the Green Line, one each on the north and south ends. By 2004, more formal Second Phase plans were developed; the Blue line was cut back and did not cross the Duwamish, but the Red line was extended west to meet a new branch of the Blue line running south from Delridge. In addition, an alternative central north–south Rainbow corridor was added, running from downtown to the University District and continuing on to Northgate and Lake City, approximately following the route of I-5. Green Line The proposed Green Line ran mostly north-south from Ballard through Magnolia, Queen Anne, Seattle Center, Downtown, Pioneer Square, Chinatown-International District, then turned west and terminated into West Seattle. Planned expansion Future extensions on the Green Line could have taken it east (from the north terminus at Crown Hill) to Northgate and south (from the south terminus at Morgan Junction) to the Vashon Island Ferry Terminal. These were later designated the Pink North and South Corridors, approximately , respectively. Additional planned lines included: Gold: north–south, connecting Lake City, UW, Capitol Hill, Chinatown-International District, and Downtown. Multiple alignments and phases were studied.
