In November 1915, the New York Public Service Commission approved plans for the construction of Section 2 of the line, which would be its elevated section, and opened it up to bids on November 30. The contractor for the section was expected to complete work on it within eighteen months. As part of the construction of this section of the line, a new bridge would be built over the Bronx River, which would be above high tide. Permission to construct a bridge over the river was obtained from the federal government after marked negotiations. At the time, work on Sections 1 and 1A, between 138th Street and Park Avenue and Southern Boulevard and Whitlock Avenue, was 75 percent complete.
