NEW YORK, NY — As his very first move as Mayor, Zohran Mamdani announced the appointment of transportation leader Mike Flynn as Commissioner of the New York City Department of Transportation (NYC DOT) immediately following his swearing in during a midnight ceremony in the old City Hall subway station. Flynn brings more than two decades of experience across the public and private sectors, helping cities envision and implement transportation systems that advance economic opportunity, social equity, and environmental sustainability.
“High-quality, reliable public transit and safe, well-designed streets allow New Yorkers to get to work without worry, travel on multiple modalities, receive the daily necessities they need, and explore new corners of the five boroughs," Mamdani said. "Our city deserves a Department of Transportation Commissioner that recognizes the critical role that street infrastructure, road design, and excellent public transportation play in making this city an affordable, safe, and dignified home for millions. That is the leadership I see in Mike Flynn, who has spent decades improving the way we walk and ride through our city — and will continue this work in City Hall.”
Most recently, Flynn led the New York office of TYLin City Solutions (formerly Sam Schwartz Engineering), where he supported teams of engineers, planners, designers, and community outreach specialists working across disciplines to solve complex transportation, development, and infrastructure challenges throughout the New York City region. As Vice President and Sector Manager for New York and the Northeast, Flynn oversaw major projects at the intersection of mobility, land use, and public space.
Previously, Flynn spent nearly a decade at the New York City Department of Transportation, where he held senior leadership roles including Director of Capital Planning and Project Initiation. In that role, he guided the planning and delivery of major capital street improvement projects supporting traffic safety, bus priority, and new public spaces citywide. Earlier at NYC DOT, Flynn worked on pedestrian and bicycle programs and transportation planning initiatives that helped reshape how New Yorkers move through the city, including leading the development of the City's first Street Design Manual.
“I am honored by the trust Mayor Zohran Mamdani has placed in me to lead the Department of Transportation and work alongside this team to deliver for New Yorkers," Flynn said. "Transportation is essential to affordability and quality of life. It determines how people get to work, school, and home safely. I look forward to building a DOT that moves faster, puts safety first, and delivers real wins for working New Yorkers.”

In addition to his work in government and the private sector, Flynn served for nearly eight years as a Visiting Professor in Pratt Institute’s Programs for Sustainable Planning and Development, where he taught courses focused on urban planning, transportation, and sustainable city design.
He holds a Master of Science in city and regional planning from Pratt Institute and a Bachelor of Arts in computer science from the University of Vermont.
“RPA applauds the Mamdani Administration for appointing Mike Flynn as DOT Commissioner," said Kate Slevin, Executive Vice President of Regional Plan Association. "He is a well-respected expert and leader in city transportation policy, and we are excited to help him carry out a vision for better bus service and safer streets.”
“Mike knows the agency, the city, and its streets from the inside out,” former NYC DOT Commissioner Janette Sadik-Khan said. “Mike will be a strong voice for Mayor Mamdani and for all New Yorkers in making transportation work for them, and for turning proposals into projects in the ground that will make the city’s streets safer, more accessible, and affordable."
