The Postal Service took the uncommon step of suspending mail supply in lots of locations, and in southeastern Minnesota, even the snowplows had been idled by the climate.
The bitter chilly was the results of a cut up within the polar vortex , a mass of chilly air that usually stays bottled up within the Arctic. The cut up allowed the air to spill a lot farther south than regular. In reality, Chicago was colder than the Canadian village of Alert, one of many world’s most northerly inhabited locations. Alert, which is 500 miles (804 kilometers) from the North Pole, reported a temperature that was a few levels greater.

Detroit is within the second yr of a $500 million program to rehab its water and sewer system. Final yr, 25 miles (40 kilometers) of water mains had been changed.
“Water pipes are brittle. The extra years they’ve gone by the freeze-thaw cycle,” the higher the stress and pressure, stated Greg DiLoreto, a volunteer with the American Society of Civil Engineers and chair of its committee on American infrastructure.
Pipes laid a century in the past have far exceeded the life span for which they had been designed, stated DiLoreto, who described the getting older course of as “residing on borrowed time.”
“Once we put them in — again at first — we by no means thought they’d final this lengthy,” he stated.
The identical freeze-thaw cycle beats up concreate and asphalt roads and bridges, leading to teeth-jarring potholes.
