City transportation officials are asking New York residents for input on how to improve the Brooklyn-Queens Expressway.

Dozens of advocates and elected officials braved the cold in Williamsburg to gather feedback with the first of three planned “walk and talk” events organized by the group Transportation Alternatives.

Representatives of the group hope the series of events will boost community engagement around the crumbling expressway.

“The BQE was a Robert Moses legacy that cut through our neighborhoods, that has created environmental harm for 100 years,” said Elizabeth Adams, of Transportation Alternatives. “We cannot continue to have environmental health impacts, to have higher rates of city pollution than citywide average…What we're doing here today is saying we can do better. We need to change this.”

Last fall, the Adams administration announced a plan to fast-track the revamping of a small portion of the BQE owned by the city. However, advocates say transportation officials need to ensure the interests of communities all along the BQE are taken into account.

Over the next few weeks, Transportation Alternatives is inviting members of the community to join them on walking tours around different stretches of the BQE to discuss ongoing issues with the expressway and ways to improve it.

“We're bringing people together, collecting information in a whole host of ways to envision what we need to change,” said Adams.

The next set of events are scheduled for March 4 at the Susan Smith Mnkinney Steward Park and March 18 at the Cough Triangle.
