The Long Island Rail Road completed maintenance on the Manhasset Viaduct on the border Great Neck and Manhasset over the weekend, MTA officials said, to ensure the stability of the bridge.
The viaduct is the steel-stringer bridge, first built in the late 1890s, that runs over Manhasset, the Village of Thomaston in Great Neck, Manhasset Creek and Bayview Avenue.
Sarah Armaghan, and LIRR spokeswoman, said all their bridges undergo regular maintenance to make sure they stay safe. In this case, she said, engineers tightened the hook bolts connecting the track timber to the bridge structure.
The viaduct is structurally safe, she added.
Consequently, according to an MTA press release, train service on the Port Washington Branch between Penn Station and Great Neck had been reduced to hourly from half-hourly. Buses substituted for train service between Port Washington and Great Neck.
The MTA had advised customers to plan for up to 25 extra minutes of travel time.
These changes were active from Saturday, July 21, at 12:17 a.m. to Monday, July 23, at 12:52 a.m.
Customers going westbound at Port Washington, Plandome and Manhasset stations had to board buses up to 25 minutes earlier than normal train times. Customers at Great Neck, meanwhile, had to transfer to westbound trains.
Anyone heading eastbound to Manhasset, Plandome or Port Washington had to transfer to buses at Great Neck.
