The de Blasio administration announced Wednesday the 2020 protected bike lane plans for the borough.

As part of the Green Wave plan, the plan calls for 30 miles of new protected bike lanes in New York City. Brooklyn itself will see at least 10 miles of bike lanes.

"This infrastructure will make things safer for the people who are on bikes,” says Eric McClure, of StreetsPAC. “It will encourage people who aren’t on bikes yet to take up cycling as a way of getting around the city and commuting, and that will benefit all of us and benefit New York City.”

Cyclist deaths in the borough last year reached nearly 20 fatalities.

The planned projects include Fourth Avenue in Park Slope; Gowanus and Flatbush Avenue in Prospect Park; Fort Hamilton Parkway in Windsor Terrace; and Meeker Avenue in Williamsburg and Greenpoint.

According to Vision Zero data, a single mile of Gerritsen Avenue that saw four speeding-related fatalities from 2007 to 2016 has not had any fatalities since the Department of Transportation added a two-way protected bike lane and other safety improvements.

That's why the city's DOT Commissioner Polly Trottenberg said she knows the new projects will make a difference.

"We really have seen the results on the ground. It can really, really save lives," Trottenberg said.

Trottenberg added that residents can expect more protected bike lane plans to be announced later in the year.
