The document proposes a 20 mile at-grade Metrorail extension from Dadeland South Metrorail Station to SW 344th St along an existing Transitway. It will include 14 stations, transit-oriented developments, and park-and-rides. Some intersections may be grade separated. 136 new Metrorail cars will be retrofitted with pantographs and no new railyard will be required. Examples of other at-grade light rail systems are described such as Expo Line in Los Angeles and Red Line in Houston.
