Tuesday's snow causes problems for MoDOT, IDOT

ST. LOUIS, Mo. (KMOV.com) -

The timing of Tuesday's snow storm couldn’t have been any worse for The Missouri Department of Transportation (MoDOT) and The Illinois Department of Transportation (IDOT) when it comes to snow removal. It hit during rush hour and caused traffic across the entire St. Louis area.

IDOT crews spent much of Wednesday trying to get the remaining snow off the roadways before a potential big re-freeze. The crews pre-treated roads before the  snow with a mixture of salt and chemicals.

But it wasn't an easy call.

“We were fortunate the forecasts were fairly accurate and temps stayed in the range,” IDOT’s Joseph Monroe said. “If it would have dropped further it would have been a bad decision. Hindsight's 20-20, after you have all the info we were probably fortunate that we pre-treated if one of those variables goes against us we would have made a very bad decision.”

MoDOT decided not to pre-treat roadways since a "dry snow" was predicted.

“And because we didn't pre-treat it it just blew off the road,” MoDOT's Mark Croarkin said. “We really didn't have to start fighting the storm for the first hour or two of snow. If we'd have pre-treated it all would have stuck and we would have been plowing earlier. I really think it was a good decision not to pre-treat yesterday.”

Other street departments News 4 spoke with said it's a tough call and difficult to compare the game plan from one department to another. The timing of the snow, snowfall amounts, temperature and traffic patterns all have to be considered.

“It really depends on your location, your weather forecast, the comfort level you've got, and the chemicals you're using,” Deanna Venker, St. Louis Commissioner of Traffic, said. “It's going to depend on has it rain recently not rained recently, is it a wet snow, a dry snow, how cold is the pavement?”

A spokesperson with St. Louis County said every storm brings its own issues in terms of timing and the type of snow that falls.
