Mayor Bill de Blasio announced that the NYC Department of Transportation will implement major bicycle and pedestrian accessibility improvements on the Brooklyn Bridge starting Monday.

The project includes removing the innermost Manhattan-bound car lane on the bridge and transforming it into a two-way bike lane.

Drivers who usually access the bridge from Downtown Brooklyn are advised that they may have to change their commute route during and after construction.

This project is part of de Blasio's commitment to install 30 miles of protected bike lanes citywide to offer safer routes for cyclists.

Pedestrians who walk and run on the bridge will also have more space.

The Brooklyn Bridge protected bike lane project was first announced in January as part of de Blasio's State of the City address.

“Bridges for the people is a beautiful reimagining of New York City’s most iconic bridge,” said de Blasio. “Before the Brooklyn Bridge was last reconfigured in 1950, it carried 400,000 New Yorkers every day—but completely replacing trolleys with car lanes reduced the number of daily bridge users by more than half. By adding new protected bike lanes on the bridge, we will finally begin to re-balance that equation, supporting more sustainable transportation for decades to come.”

The construction will begin Monday evening and is expected to be completed by early fall.
