The city is putting $250 million toward changing four dangerous major outer borough streets that caused 249 deaths in four years.

The money for the Vision Zero Great Streets program will target the notorious Queens Boulevard, 4th Avenue in Brooklyn, Atlantic Avenue in East New York and Grand Concourse. Residents can expect to see work on major changes -- bigger pedestrian areas, green medians and better defined bus and bike lanes -- to begin in 2017.

"We have some shorter term safety projects that we're going to try to get underway this year," DOT Commissioner Polly Trottenberg said at the City Council on Thursday. "But in terms of big grand revisioning ... we're still very much working with the community."

A 7.2-mile stretch of Queens Boulevard will get most of the money, $100 million.

Councilwoman Karen Koslowitz, who represents part of the thoroughfare, heaped praise on the DOT for its work there.

"My dream in life is to not call Queens Boulevard the 'Boulevard of Death,'" she said.
