This coming weekend is the first of four in May and June when the Long Island Rail Road plans to install new concrete railroad ties between the Locust Valley and Oyster Bay stations, the MTA said in a release.
That means buses will replace trains on the entire Oyster Bay branch from 12:40 a.m. Saturday through 3:30 a.m. Monday, when train service will be suspended for what the Metropolitan Transportation Authority calls "a major infrastructure improvement project."
The work is also scheduled for the weekends of May 17 to 19, May 31 to June 2 and June 14 to 16, when buses again will replace train service.
Traveling time will be up to 40 minutes longer for westbound passengers, who will board buses or vans at stations from Oyster Bay through East Williston, heading to Mineola, where train service resumes.
Eastbound passengers, who will spend up to 27 minutes longer travel times, will board vans or buses at Mineola, heading for East Williston and beyond, the MTA said.
