Avenue and Boston Road. The extension, called "Route 106", was proposed to run elevated over Bronx Park in the lower-deck of a viaduct connecting 205th Street and Burke Avenue. The first stop on the extension would have been at White Plains and Gun Hill Roads. The Second System plans had multiple IND lines criss-crossing the five boroughs; however, the country was in the midst of the Great Depression, and the city had neither the money nor the need to either extend the line east of 205th Street or make the line four tracks. A second plan in the 1930s had an additional extension along Burke Avenue to the New York, Westchester and Boston Railway, running north along the railroad to Dyre Avenue. Preliminary engineering work for the extension along Burke Avenue took place in 1937 and 1938. The city, however, found it easier and less expensive to purchase the railroad (now the IRT Dyre Avenue Line) and connect it with the IRT White Plains Road Line, which hampered the Burke Avenue−Boston Road extension of the Concourse Line to Baychester Avenue. In the 1960s and 1970 under the city's Program for Action, it was proposed to extend the line a short distance to White Plains Road and Burke Avenue, at the IRT White Plains Road Line. Financial troubles also caused the plan to be aborted.
