NEW YORK - City Officials are calling on Mayor Bill de Blasio to create a 24-hour traffic plan during the L train shutdown.

Brooklyn Borough President Eric Adams and Manhattan Borough President Gale Brewer sent a letter to the mayor addressing their concerns.

They're asking the city to keep the alternatives running 24/7, in order to keep up with the busy communities.

They're also asking for that plan to come quickly, in order to ease uncertainty.

The city's current plan is to restrict travel on the Williamsburg Bridge to buses, trucks, and carpools.

It will also restrict traffic on 14th street for buses.

The repair of the Canarsie Tunnel causing the L train shutdown is expected to begin next April, for 15 months.
