On December 2009, Oklahoma City voters passed MAPS 3, the $777 million (7-year 1-cent tax) initiative, which will include funding (appx $130M) for an estimated 5-to-6-mile (8.0 to 9.7 km) modern streetcar in downtown Oklahoma City and the establishment of a transit hub. It is believed the streetcar would begin construction in 2014 and be in operation around 2017.
