on the line from 20 trains per hour (tph) to 24 tph, as well as permitted the installation of countdown clocks, which show the amount of time until the next train arrives. 14th Street Tunnel shutdown In January 2016, the BMT Canarsie Line between Bedford and Eighth Avenues was proposed for a partial or full shutdown so that the MTA could repair tunnels damaged by Hurricane Sandy in 2012. The repairs are slated to start in April 2019 and would replace damaged communications, power and signal wires, third rails and tracks, duct banks, pump rooms, circuit breaker houses, tunnel lighting, concrete lining, and fire protection systems. The renovations would cost between $800 million and $1 billion. There were two options: a partial closure for three years or a full closure for 18 months. It was later announced that the MTA had chosen the 18-month full closure option. To provide alternate service, the MTA devised preliminary mitigation plans in which it proposed adding shuttle bus, ferry, and subway service; adding bus and high-occupancy vehicle lanes; extending train routes; and providing free or improved transfers. The MTA named Judlau Contracting and TC Electric as the project's contractors on April 3, 2017. At this time, the duration of the shutdown was shortened to 15 months, so the shutdown would begin in April instead of in January. In June 2018, as part of a lawsuit settlement, additional changes were made to the shutdown mitigation plans. The shutdown was expected to begin on April 27, 2019. In January 2019, the shutdown was changed to limited closures between Third Avenue and Bedford Avenue on late nights and weekends. It was expected to last about 15 to 20 months. On April 26, 2020, New York governor Andrew Cuomo announced the completion of the project, months ahead of schedule. Service patterns Service patterns over this line have varied little through the years; initially, trains ran over the Broadway Elevated from the ferry in Williamsburg (later extended into Manhattan), through Manhattan Junction and on to Canarsie. Then when the subway opened, two services ran from Canarsie to Manhattan: the original route on the Broadway Elevated and the route to 14th Street as the 14th Street-Canarsie Line. In 1936, due to the institution of new lightweight subway-elevated equipment, a new rush-hour-only service was inaugurated from Eighth Avenue and 14th Street to Lefferts Boulevard at the east end of the Liberty
