The Queens Boulevard Line was one of the first built by the city-owned Independent Subway System (IND), and was planned to stretch between the IND Eighth Avenue Line in Manhattan and 178th Street and Hillside Avenue in Jamaica, Queens. The line was first proposed in 1925. Construction of the line was approved by the New York City Board of Estimate on October 4, 1928. Approval of the section of the Queens Boulevard Line between the intersections of 137th Street (now the Van Wyck Expressway) and Hillside Avenue was held up by a month during late 1929 because of a dispute over a spur that would run south to Rockaway Boulevard. Some property owners wanted the spur to run under Van Wyck Boulevard, while others wanted it to run under Sutphin Boulevard to the east. On December 23, 1930, the contract for the construction of the section between 137th Street and 178th Street—Route 108, Section 11—was let. This section included the stations at 169th Street, Parsons Boulevard, Sutphin Boulevard, and Van Wyck Boulevard. The contract for this section was awarded to Triest Contracting Corporation. The line was constructed using the cut-and-cover tunneling method, and to allow pedestrians to cross, temporary bridges were built over the trenches.
