BROOKLYN — Part of the N line express tunnel in Brooklyn will be closed for a year starting 2018 to repair rusted beams, according to officials.
Workers will replace corroded columns that support the tunnel between the 36th and 59th streets starting in May 2018, MTA and local officials said. The beams became corroded from rain water running into subway grates along the median strip on Fourth Avenue.
The Prospect Avenue and 53rd Street stations will also be shut down this year for about six months for rehabilitation work, according to Community Board 7 District Manager Jeremy Luafer, and the express tunnel will need to remain open during that time.
Workers will also install a new elevator at the 59th Street station, but that will not cause it to be shut down.
The city will also make repairs to the median along Fourth Avenue to prevent excess water from leaking into the stations, Laufer added.
The N will run on the local R line during the closure and continue to terminate at Coney Island.
