Top officials with Mayor Zohran Mamdani’s Department of Transportation (DOT) on Tuesday blamed the agency’s years-long struggles to meet legally mandated targets for adding new protected bus and bike lane miles on the former Mayor Eric Adams’ administration, while pledging to “do better” going forward.

DOT Commissioner Mike Flynn faced sharp questions from members of the City Council’s Transportation Committee during a March 3 hearing probing why the agency has failed to create the number of protected bus and bike lanes required by the 2019 Streets Master Plan year after year. The plan, which mandates the city add 150 new miles of protected bus lanes and 250 new miles of protected bike lanes between 2022 and this year, was passed by the council in 2019.
