When construction of the subway started in January, 1920, three contractors had been selected by the Rapid Transit Commission to complete the work: D.P. Foley General Contractors, Hickey Brothers and Fred R. Jones Company. The construction of the 16-mile subway loop was separated into nine sections, with contractors bidding for work on each section. One section might include construction of tunnels within the old canal bed for underground subway tunnels and stations, while another section might require construction of tunnels through a hillside, above-ground station construction, or grading of terrain for tracks to be laid in the open.
