From Richard White of the Park Slope Civic Council:
NYC Dept. of Transportation is proposing dangerous traffic-flow changes that will have a severe impact on Park Slope. They include making 7th Avenue a one-way southbound street and making 6th Avenue a one-way northbound street, with the increased speeds and potential for more serious accidents that those changes imply. If you care about your own and your children's safety, as well as the residential quality of our neighborhood, you must show up on March 15th to let DOT know how unacceptable their proposals are.
Details on the meeting:
Presentation and discussion of a proposal by the Department of Transportation to convert 7th Avenue (between Flatbush Avenue and Prospect Avenue) from a two-way street to a one-way southbound street and 6th Avenue (between Atlantic Avenue and 23rd Street) from a two-way street to a one-way northbound street.
Presentation and discussion of a proposal by the Department of Transportation to eliminate one northbound and one southbound travel lane from 4th Avenue (between Dean Street and Prospect Avenue) and replace them with improved left-turn turning lanes.
