MANHATTAN - Construction is bringing some Manhattan subways to a screeching halt this weekend.
The biggest disruption will come on the 7 line. Trains will not be running between Times Square and Queensboro Plaza until 5 a.m. Monday in order to preform signal repair work and repair leaky tunnels, according to the MTA.
The signals along the line are 50 to 90 years old and will be replaced by a state-of-the-art system, a project which is expected to take until 2016 to complete.
Riders are encouraged to take the N, S or shuttle bus service instead.
There are also no 1 trains running between 168th Street in Washington Heights and 242nd Street in The Bronx. Straphangers can take the 2, 3, or A instead.
The 1 also isn't running from 14th Street to South Ferry. Alternatives include the 2, 3 or shuttle bus, the MTA said.
