(Walton, Ky.) - Traffic trouble on Interstate 75 has the highway closed at the Walton exit in southern Boone County Monday morning.

Dispatchers say two tractor trailers collided on Mary Grubbs Highway just beneath the interstate overpass at about 3:00 a.m. Nobody was injured in the crash, but fuel was leaked as a result.

Traffic on northbound I-75 is being directed off the interstate using the ramps at May Grubbs Highway, then getting right back on.

It is unclear when I-75 may reopen.
