Historic Downtown Plano focuses on the city's main mercantile area of Mechanic (Fifteenth Street) and Main (K Avenue) and the surrounding heritage districts of Haggard Park, Old Towne, and the Douglass Community. Incorporated in 1873, downtown Plano has endured at least five major fires, the Great Depression, closure of the interurban railway, and retail and corporate development to the west of the area. In recent years, downtown Plano has benefited from ongoing redevelopment and revitalization as an urban transit village with the Dallas Area Rapid Transit (DART) light rail train service to the area—taking us back to those days of old.
