Finalists in a competition to improve the crowded Brooklyn Bridge experience for pedestrians and cyclists are proposing a new glass walkway, “microforests” at either end and even car bans.

All six finalists, whittled from about 250 entries in a contest held by the New York City Council and urban-design nonprofit the Van Alen Institute, would turn the 19th-century thoroughfare into a space for culture, lingering and civic engagement.

Crossing the Brooklyn Bridge on foot and by bike has become trickier over time. Between 2008 and 2015, on weekends, pedestrian traffic over the bridge nearly quadrupled, while cyclist traffic more than doubled, according to a 2017 report by the New York City Department of Transportation.
