A Locally Preferred Alternative (LPA) is the selected physical design concept and scope for a major corridor transit investment. For the Red Line in Baltimore, the decision on the LPA identifies the transit mode (bus or light rail), and the location and description of the alignment. The LPA will also generally describe the proposed location of stations, the operating plans for the transit service (hours of operation, how often vehicles run, etc.), and any design options to be further evaluated during the next phases, Preliminary Engineering and Final Design.
