Straphangers gathered in Manhattan on Wednesday evening to express concerns over the upcoming L train shutdown.

It was the last in a series of informational meetings that the MTA and the city transportation department hosted about the Canarsie Tunnel closure.

Starting in April 2019, L train service will be suspended for 15 months between 8th Avenue and 14th Street in Manhattan and Bedford Avenue in Brooklyn. Crews will repair damage that Hurricane Sandy caused.

Local residents gathered at Our Lady of Guadalupe Church on 14th Street in Chelsea were very concerned about what the shutdown will mean for their neighborhood.

"If we don't provide an alternative for people to take into Manhattan, or to take from different points in Manhattan, everybody will get in their private cars or they'll get an Uber or they'll get a Lyft and we're going to wind up with a sea of cars here," one resident said outside the church. "It's going to be massive gridlock."

"I think most people understand, absolutely, that we have no choice, we have got to do this work. And they understand that what we're trying to do here is get it right," Andy Byford, the president of New York City Transit, said to members of the media during the meeting. "As I've said before, the plan's not set in stone. The whole point of having these exercises is to listen to feedback and refine the plan to make sure we get it right."

The MTA plans to beef up other area subway service and add more bus and ferry service to help L train riders get around.
