MISSOULA, Mont. -

The city of Missoula announced an ambitious goal Thursday to have all city streets plowed by the end of the day.

Street Superintendent Brian Hensel said another incoming winter storm isn't giving them much of a choice.

"These big storms are a terrible inconvenience. I know a lot of people are frustrated,” said Hensel. “We feel the frustration. My guys have all been working extra hours and overtime. We're doing the best we can, and putting every effort."

Hensel said the roads department has at least 19 pieces of equipment on the roads and crews working overtime since a storm earlier this week dumped more than 11 inches on Missoula in 48 hours.

The city classifies streets by their level of traffic, and use that to prioritize where plows are sent, said Hensel.

40 percent of Missoula’s roads needed plowing at the start of Thursday. We’re told by 5:30 p.m., crews had all but 15 percent completed.
