The Triborough Bridge is mobile, and therefore officially cooler than its counterparts.
It's equipped with a ridiculously cool draw-bridge system that rises for big boats that need to pass through the East River. The mechanical system typically sits 55 feet above water.
Provided there is advanced notice, the bridge is required to raise for marine traffic at any time and can rise up to 136 feet above water in order to let vessels through.
Construction rooms and beauty aren't typically associated with one another, but the construction rooms in the bridge are exquisite.
The expensive gears and machinery are extremely well-kept and look as if they are new.
