ERLANGER, Ky. -- Road crews say they've done all they can Tuesday to clean and salt Tri-State roads, but another dangerous element could threaten drivers: ice.
By Tuesday evening, most main roads and interstates were clean and clear. But with temperatures falling , officials say ice could plague late night drivers.
The Salt Barn in Erlanger, Ky., was like a revolving door Tuesday morning -- truck after truck came through to load up on the blue stuff.
John Crouch began putting salt down at midnight and was still going 12 hours later.
In Northern Kentucky, more than 60 plows worked to divvy up some 22,000 tons of salt Tuesday.
"Our main focus is still getting our secondary routes open and hopefully have a dry pavement like this right now,” said Kentucky Transportation Cabinet spokeswoman Nancy Wood. “That's our ultimate goal… but there's still a lot of cleanup to do, so they're working on it.”
Wood said most crews went home after rush hour.
"We're pretty much at the mercy of the colder temperatures,” Wood said. “There's not too much more that we can do."
Road crews said the salt dropped Tuesday will go a long way in making local roads safer from ice.
