Tappan Zee Bridge demolition impacts early morning Metro-North servicePosted: Updated:
The Tappan Zee Bridge demolition impacted the Hudson Line train service this morning.
Train service between Irvington and Tarrytown stations was closed from around midnight through 7 a.m.
The closings were due to crews continuing work to dismantle the Old Tappan Zee Bridge.
Crews are using a super crane to lift sections of steel above Metro-North's Hudson Line.
Some of those steel pieces weigh around 1,300 tons.
Demolition of the old bridge is expected to last about a year.
The new bridge is expected to open sometime in 2018.
