Work to repair damage done by a massive landslide to Interstate 75 in northern Tennessee will continue through the weekend. It’s blocked the southbound lanes of that major artery and has changed the casual conversation at Kentucky’s welcome center. The man who supervises the Welcome Center operated by the Commonwealth just north of the state line takes a lot of questions. But since March 8th, when a landslide partially blocked I-75, David Cox says the nature of those questions has changed. Cox says the first question asked by many northbound motorists is ‘what’s wrong.’
