L has frozen over.

Mayor Bill de Blasio announced Friday that he agreed with Gov. Andrew Cuomo's plan to avert a shutdown on the subway line linking Williamsburg to the East Village. De Blasio brushed off reports that his fellow Democrat's proposal, which will instead involve several months of overnight and weekend work while the L continues to run, has bypassed normal bureaucratic procedures and could create safety hazards and horrendous wait times along the trendy train route.

"The new idea that was put forward by the governor caught us all by surprise, but we did spend a lot of time trying to understand it and make sure we were comfortable," the mayor said during his weekly appearance on WNYC. "We do believe that the new approach is better. We support it."

De Blasio noted that his team had cooperated with the Metropolitan Transportation Authority in sketching out plans to compensate for the inconveniences expected from a 15-month shutdown. These included reorganizing bus routes and painting new bike lanes on city streets.

The mayor said on the radio that his administration was now "sorting out" which of these changes it would retain under the new vision.

Under the governor's conception, workers will patch up concrete lining fractured during 2012's Superstorm Sandy—instead of replacing it—and install new overhead electrical cables without removing the old ones. At the press conference announcing the proposal earlier this month, Cuomo—who controls the MTA—disagreed with his appointed Acting Chairman Fernando Ferrer over whether the body's board would need to sign off on the decision.

As of now, the MTA's position is that no such approval vote is necessary, even though the new plan involves renegotiating the $500 million deal it had already signed with Judlau Contracting.
