actually I support this because they're just turning light off on interstates that are not heavily used. It says "
It carries 380,000 vehicles a day, many of them from out of state" - that is relatively light! If this is the road where there are more than 800,000 vehicles a day.. then yes keep the light on.
You don't really need to keep ALL lights on... you can just keep light on every certain yards... just like emergency telephone is placed every several miles I prefer driving on unlit interstate because it is less distracting.
They really should invest in energy-saving way to light the highway. I read about a very interesting article about installing LED lights along the highway... which is exactly like airport runaways. The research study shows that this is safer. see below - it is economically and environmentally friendly.
