"Reduced Salt Area "on Interstate highways.. What does that mean?

Question

I came across boards reading. "Reduced Salt Area "on Interstate highways .. What does that mean ?

Answer 1

When theres a blanket of snow, highway maintenance crews routinely lay down a fine layer of salt to melt the ice, and reduce the chances of your tires no longer in traction with the pavement, but is on a layer of thin ice.  With salt, you instead drive on water, which is melted ice.  With reduced salt, then you're likely to run across areas of thin ice, where you loose traction and have no control of your vehicle.   With all the budget constraint state and local coffers are experiencing, its more than likely the highway maintenance crew doesn't have the  $$ to buy enough salt  this season.

Answer 2

Hehe, okay, CEO.  Nice try.  Road crews always have enough salt, government will complain about the additional cost, but they will do everything possible to have salt available.  Imagine the lawsuits if the government just up and stopped clearing the interstates.  They have an obligation to clear interstates because the primary function of the interstate is to provide the military with a means of rapid mobilization in the event of a national defense crisis.  They'll lose more in federal funding than a few loads of salt will cost, trust me.  

Reduced salt area means the road crews are spreading less salt to reduce salt runoff.  Typically, it's to avoid contaminating a fresh water source nearby that serves either a community or is a watering hole for local wildlife.  Fresh water fish and vegetation are sensitive to salt levels and could easily die if runoff from highways is too high.  It took us a long time to learn that lesson...
