MTA New York City Transit (NYCT) announced that the massive reconstruction work needed to the Canarsie Tunnel, which carries the L train under the East River between Brooklyn and Manhattan, will require a full closure of the tunnel for 18 months starting no sooner than 2019.
The decision to do the work under a full 18-month tunnel closure, instead of a one-track, three-year closure, was made based on a detailed operational review, and only after significant community engagement to consider all adverse impacts, according to the agency. Serious consideration was also given to consequences of unplanned outages that would occur if one track was closed for three years.
