Approximately 280,000 square feet of metal tunnel surfaces and equipment were cleaned of salt residue left by Sandy and corroded metal was replaced, the Port Authority of New York & New Jersey said.
The World Trade Center and Exchange Place stations will be closed between Friday night and early Monday morning from Nov. 8 to Nov. 10., Nov. 15 to Nov. 17 and from Nov. 22 to Nov. 24.
The resumption of the Hoboken to World Trade Center service means weekday PATH service has returned to its pre-Sandy schedule.
The line had been running weekdays from 5 a.m. to 10 p.m. to accommodate overnight work related to Superstorm Sandy.
All of the escalators were offline Tuesday morning at the Exchange Place PATH station in Jersey City one day after one of them suddenly reversed direction and five people were injured.
Investigators were looking into the possibility that damage from Superstorm Sandy was responsible for the horrifying mishap.
Nearly four weeks after Superstorm Sandy, PATH train service from New Jersey to Lower Manhattan will resume on Monday morning.
