BROOKLYN - Major improvements to the Brooklyn Bridge are underway.

The $508 million rehabilitation project aims to ease a growing congestion problem by expanding exit ramps to and from the Brooklyn Bridge and FDR Drive.

There will also be an expansion from one to two lanes as motorists get off the Brooklyn-bound bridge to Cadman Plaza West and Old Fulton Street.

The Department of Transportation plans to have all the construction, including repainting the Brooklyn Bridge, completed next year.
