Progress photographs primarily depicting the progress of construction of the steel elevated structures along Front Street and Kensington Avenue for the Frankford Elevated Railway built 1915-1922 under the auspices of the City of Philadelphia’s Department of City Transit. Images capture construction workers and horse-drawn vehicles carrying construction materials, as well as factories, businesses, residences and other buildings along the line. The majority of steel work was contracted to McClintic-Marshall Co. which received the largest construction contract for the project. Photographs may have been taken by the Department of City Transit photographer Norman M. Rolston who was assisted by J. Wesley Cooke.
