In Lincoln and Omaha, hundreds of snowplow drivers have put in long hours over the last two weeks, with each city using a different strategy to keep the streets clear. Clayton Engelman, the transportation maintenance coordinator for the city of Lincoln, says major arterials remain the city’s priority after the snow stops falling. “Once the snow stops, that's usually what we call zero hour,” Engelman said. “And then at that point, we try to get the streets, the main streets, fully cleared before we move on into residentials.”
