On the afternoon of June 30, the air in the city warmed to 44 °.
The last weekend of June in the north-east of the US came the heat. In Twitter, got a video of how the fire department of Chicago had to water the bridge on Michigan Avenue to cool it.
Such a measure was required due to the fact that from high temperatures the steel of the bridge widened and the passage for boats under the construction dangerously decreased.
It was so hot in Chicago, Illinois that the fire department needed to hose down the Michigan Avenue Bridge after the steel expanded, reducing clearance for boats. https://t.co/6XTbPX8219 pic.twitter.com/B6880ckLR5
