Interstate Highways Are Snow Traps
Under normal conditions, the United States Interstate Highway system moves people and goods efficiently from one place to another.
Along with us dweebs in cars and small trucks, zillions of tractor trailers zip back and forth delivery goods and supplies to zillions of places and people.
Until it snows.
There's no good mechanism for getting people moving again when tractor trailers jack knife on ice, or cars slide off the highways and into ditches or other cars.
Such was the case last evening, when a snow squall froze a previously just wet section of Interstate 89 between Burlington and Montpelier. The Interstate was basically a parking lot from mid afternoon into the evening because of this mess, reports WCAX-TV. The traffic jam continued hours after the snow squall had ended, demonstrating how hard it is to untangle an Interstate highway crash.
Elsewhere yesterday, parts of Interstate 80 in Nebraska, Interstate 35 near Kansas City and Interstate 70 southeast of Manhattan, Kansas were closed due to a snowstorm Sunday, the Weather Channel reported.
More closures are possible as the storm heads northeast into the Ohio Valley and eventually southern New England.
Snow squalls are the worst, because they cause rapid changes in road conditons and sudden white out conditions. That's still a threat here in Vermont Wednesday, which would make it the third time in a week that heavy snow squalls either shut down parts of Vermont highways or threatened to. Wednesday's snow squalls here in Vermont might be the worst of the bunch. (There were problems with snow squalls last Thursday and again yesterday.)
The limited access of Interstate highways that make them safer with no cars merging from side streets. But the only way to get cars trapped behind snowy wrecks, or any kind of wreck is to wait until the mess is cleaned up so people can progress to the next exit at least.
Sometimes, people are directed into those little patches of asphalt connecting opposite lanes of highways where cops wait for speeders. Then the motorists can go basically U-turn back toward their starting point but that takes a long time to accomplish too.
Police and first responders must give priorty to getting the injured to hospitals, investigating the cause of the crash, and getting things cleared in a safe manner that doesn't cause more injuries. Plus, they often don't have the manpower to figure out a way to move all the stuck traffic behind the wrecks.
That's why people are often stuck for hours behind Interstate crashes. They're not the highest priority, I'm afraid.
My advice, and it isn't perfect: Make sure you have a full tank of gas, especially in the winter, before you venture out. If they say snow squalls are on the way or are already here, stay home. Try to listen or hunt for traffic alerts so you can avoid gummed up areas.
As we enter a winter full of ice storms, snowstorms and snow squalls, you, too might be stuck on the Interstate for a long time. They only way to manage it is to be prepared.
