More weekend PATH station closures are on the way. This time, the service changes will last nearly two years.

The Port Authority announced that its World Trade Center PATH station will close on weekends, starting in January 2019 and continuing through December 2020. The closures are necessary to replace equipment and rebuild tunnels that were “severely damaged” in Hurricane Sandy more than six years ago.

Beginning Jan. 5, the station in lower Manhattan will close at 12:01 a.m. on Saturdays and will reopen the following Monday at 5 a.m. after each weekend of work. The station will remain open on holiday weekends.

Repairs will include replacing train tracks and communications infrastructure in the tunnels below the Hudson River. At the World Trade Center station, which is housed in the state-of-the-art Oculus transportation hub, officials say corrosive salt water ruined much of the underground electrical and mechanical systems.

While the work is carried out, service to World Trade Center will end at Exchange Place in Jersey City. From there, riders will be offered free ferry service at the nearby Harborside Ferry Landing in Jersey City. Ferry service will run to and from the Brookfield Place Ferry Terminal each Saturday and Sunday from 7 a.m. to 11:30 p.m.

PATH service on the Journal Square-33rd Street line via Hoboken will follow a regular weekend schedule, with additional service provided during the overnight hours when the ferry is not in operation.

“We understand the loss of the WTC PATH station on weekends will cause hardship and inconvenience for many of our customers, but these repairs are vitally important to our continuing effort to overcome the worst storm we’ve experienced here in our lifetimes,” PATH General Manager/Director Michael Marino said in a statement.

The weekend closure of the World Trade Center station is the latest in a series of weekend service changes PATH has undergone in recent years.

The system’s 33rd Street line was shut down on weekends from mid-July to October while crews continued to install and test Positive Train Control, a federally-mandated safety system. In 2016, weekend service on the 33rd Street line was suspended from September to December for the initial installation of PTC.
