Relief could be on the way for subway riders who are forced to wait on sweltering platforms during the summer months. Mayor Zohran Mamdani, Governor Kathy Hochul and the MTA announced plans for a feasibility study that would help reduce temperatures underground, while trapping the heat to warm nearby buildings during the winter months. The study will center around the Brooklyn Bridge-City Hall station and Chambers Street 4,5,6, J and Z lines, deemed to be one of the hottest subway stations in the city. On average, the city says temperatures have soared to 96 degrees on a given summer day. "There are few feelings worse than escaping the extreme summer heat only to find yourself on a subway platform that is even hotter. Unfortunately, for millions of commuters that is the reality of our transit system — with some stations soaring up to 20 degrees hotter than the outside temperatures,” said Mayor Mamdani. The feasibility study is expected to kick off in early 2027 and is estimated to cost $800,000. It is being funded by revenue from congestion pricing.
