subway running parallel to the Washington Street line under Jackson Street, similarly using the tunnel located between Jackson and Van Buren Streets. Both would be tied into another subway tunnel to be dug under Clinton Street, proposed in the interim. The only construction accomplished in advance of these plans were the pair of portals in the Eisenhower Expressway median, 200 feet east of Halsted Street, constructed in 1952 simultaneously with the pair of portals for the Blue Line, and the double-wide station built at Peoria Street in 1964 to accommodate the anticipated platform north of the UIC-Halsted platform for the Blue Line. In 1951-1952, the plans were modified to use the Washington Street subway as a busway rather than as a train tunnel, while Clinton and Jackson tunnels were merged and remained a rail plan. The plan was cancelled in April 1962, although the design and placement of the Peoria Street station house went unchanged.
