Two incidents along a major interstate made for a long commute Friday morning.

Pouring rain in Bradley County made it tough for the Tennessee Highway Patrol to investigate a two vehicle crash that killed one person. It happened just before 5:00 a.m. on I-75 at exit 25.

Officials tell Channel 3 the drivers of both vehicles were from out of state.

Troopers shut down the southbound lanes for three hours as they tried to figure out what happened.

Traffic was diverted through downtown Cleveland, but some drivers like Barbara Laughtery decided to wait at home until traffic cleared.

“I figured I mind as well be at home rather than be on the road so I waited at home,” she said.

Just after the interstate re-opened, a tractor trailer fire snarled I-75 southbound traffic again. This time in Chattanooga between the Bonny Oaks and Shallowford Road exits.

No injuries were reported but you can see from traffic cameras built up quickly.

The morning's wet weather only added to the challenges drivers faced. 

Tennessee Highway Patrol reports the victim in Friday morning's fatal accident on I-75 S was Deborah Daybolt Merker, 78, of Habford, PA.

Also injured was Dylan Michael Tremellen, 21, from Lancaster, PA.  Both were wearing seatbelts.  The cause of the crash is under investigation. 

The Tennessee Highway Patrol has confirmed that one person is dead in the Friday morning crash on Interstate 75.

Traffic is being diverted off I-75 at Exit 25, then along 25th Street to Lee Highway to APD 40 and back into I-75 South. 

One lane of Interstate 75 has been re-opened to traffic, but motorist should expect some delays until traffic flow returns to normal in the area.

Tennessee Highway Patrol tells Channel 3 troopers are working a two-vehicle crash with serious injuries.
