only opened in eight of the ten cars). Upon its completion, the Worth Street station to the north was closed due to its close proximity to the platform extensions, and, as such, the station was renamed Brooklyn Bridge–Worth Street. In late 1959, contracts were awarded to extend the platforms at Bowling Green, Wall Street, Fulton Street, Canal Street, Spring Street, Bleecker Street, Astor Place, Grand Central, 86th Street and 125th Street to to accommodate ten-car trains. At the same time, work to modernize the signals and interlockings between Wall Street and 86th Street was underway. Another element of the modernization plan was the construction of a new station entrance and control building in Bowling Green Park at Bowling Green, with new stairways to the platform. On July 23, 1959, the Board of Estimate approved the contract for the construction of express platforms at Lexington Avenue–59th Street. The new platforms were intended to reduce transfer congestion at Grand Central–42nd Street, and to allow transfers between the express trains and BMT trains to Queens. Even before the express platforms were added, this station was the busiest on the line. Construction for the express station began on August 10, 1959. The two express platforms were wide and long. Along with the new express platforms, a new mezzanine was built above it to connect it to the local station, and the Broadway Line station. Two high speed escalators were added to connect the local and express platforms. Two additional high speed escalators were built to connect the local platforms with the new mezzanine. As part of the plan, the local platforms were extended to accommodate 10-car trains. In addition, new entrances and booths were added to the 59th Street ends of the northbound and southbound sides. The project cost $6.5 million and was completed three months prior than originally planned when the new platforms opened on November 15, 1962. In April 1960, work began on a $3,509,000 project to lengthen platforms on the line to accommodate ten-car trains at seven stations on the line. As part of the project, the northbound platforms at Canal Street, Spring Street, Bleecker Street, and Astor Place were lengthened from to . The platform extensions at these four stops opened for service on February 19, 1962, enabling the doors of all eight cars of trains to open on the platform. Work was still underway at two of the other
