New York bridge gets stuck open after getting too hot - midwest.social

Third Avenue Bridge, which connects New York’s the Bronx to Manhattan, got stuck in an open position due to the high heat on Monday. FDNY officers arrived in boats and fired water at the structure to try and cool down the metal, which expanded after high temperatures in the city, officials say. The incident caused major traffic delays during one of the hottest days of the year in New York but reopened on the same day.

We had a similar issue with an older bridge here in Gothenburg, Sweden. The fix was to install water sprinklers during the summer to keep the bridge from expanding too much.
Dumb question, but why is the water cooler than the bridge? Because it was underground? Or does the evaporation help because it’s endothermic?
Probably because the metal absorbed heat from sunlight and heated up considerably, but the water was room temp only.
