Maryland Department of Transportation Maryland Transit Administration (MDOT MTA) pursued an innovative solicitation approach for the Purple Line. This partnership with private industry, commonly referred to as a public-private partnership (PPP or P3), will promote the successful delivery of the Purple Line. On March 2, 2016, Governor Larry Hogan announced Purple Line Transit Partners (PLTP) as the Concessionaire for the Purple Line. PLTP is responsible for designing, constructing, operating, and maintaining the project, and the private partner will also help finance a portion of construction. MDOT MTA retains ownership of the Purple Line. The Concessionaire is comprised of three main teams:

  • Purple Line Transit Partners (PLTP) – responsible for the overall project, including financing and management of:
    • Purple Line Transit Constructors (PLTC) – responsible for the design and construction of the Purple Line.
    • Purple Line Transit Operators (PLTO) – will take over to operate and maintain the Purple Line for 30 years after completion.
