Park Street 'Subway' construction
Works Progress Administration (W.P.A.) workers constructed a pedestrian underpass at Park Street and Tremont Street in Boston, Massachusetts. From a W.P.A. Bulletin:
Boston’s WPA Park Street Subway Project, to relieve congestion in the busy downtown district, is nearing completion. Soon motor traffic will thunder overhead while pedestrians pass safely underground to the subway terminal.
