EDISON - Rain that covered the Garden State will turn into ice on untreated roads and sidewalks as overnight temperatures drop into the single digits.

The Middlesex County highway department says it is optimistic since the rain stopped early in the day. "A lot of the roads are drying, which is a good thing," says Ralph Albanir. "Route 1 looked pretty dry to me."

It is the smaller roads and ramps that officials are most worried about and preparing. Truck-loads of salt were loaded into more than 80 trucks, and are ready to go to trouble spots through the night.

In Middlesex County, crews have been spreading a calcium treatment which works better than salt, which is not effective below 15 degrees.
