The widely-dreaded L train shutdown of 2019 is still two years away, but New Yorkers who live along the line will get a preview in the not-so-distant future, according to a Friday afternoon press release from the MTA.

"New York City Transit will conduct critical repairs and preparatory work on the L Line's Canarsie Tunnel starting in May in order to ensure the tunnel can remain open until the planned April 2019 closure of the tunnel for full rehabilitation from the damage caused by Superstorm Sandy," the authority stated.

In other words: we're closing the tunnel so we don't have to close the tunnel... before we close the tunnel.

Work will take place over the weekend of May 6th, from 12:00 a.m. Saturday until 5:00 a.m. Monday, and over Memorial Day Weekend, from 12:00 a.m. Saturday May 27th through 5:00 a.m. Tuesday May 30th. Service will be suspended between 8th Avenue and Broadway Junction, with regular service between Broadway Junction and Canarsie.

"In order to minimize the impact of the outages, the work is being done on weekends because the ridership is lower and on a holiday weekend when an extra day can be utilized, which will result in one less weekend outage needed," the MTA said.

Crews are planning to replace ties on the impacted section of track, which make for a "smoother ride," according to the authority. The MTA will also survey the Canarsie tubes—a task that requires clearing the tracks and deactivating the third rail.
