CHATTANOOGA, TN. (WDEF) -- With the fourth of July holiday approaching traffic is building on the interstate highways.
Along with more trucks and cars comes more accidents, and such was the case this morning at the western base of the Ridge Cut.
There are lots of crashes there, and some are not as lucky as the two people involved this spectacular crash.
The westbound slope of the Ridge Cut can be tricky if a driver is unfamiliar with that part of I-24.
This crash apparently happened quickly as the small SUV pulling a travel trailer came over the wall and fell about 25 feet to the ground.
Workers at a nearby business heard the crash.
SHANE BAGLEY, FIRST ON THE SCENE "When I come running around the building you could see smoke just as I came around the trailer was coming off the top of the bridge..and the truck was coming down beside the bridge."
The SUV was heavily damaged and two women and a dog were trapped inside.
SHANE BAGLEY, WITNESS "When we got in there, the driver was knocked out but she came to...and the other lady who was in it was on the phone...there were some minor injuries..I don't know how bad."
Richard Matthews, one of the managers at Thermo King, was cut by razor wire as he tried to help.
LOUIS FOREHAND, WORKS NEARBY "He was going back there to try to help get people out of the car, and when other people saw his leg was just covered in blood, his pant-leg was soaked in blood..they said you need to go to the hospital."
The two women, who were traveling from Florida were not believed to be seriously hurt.
One of them even called McKamey Animal Shelter to check on the 6-year old brown lab who was taken there for treatment of minor injuries.
KAREN WALSH, EXEC. DIR., MCCAMEY ANIMAL SHELTER "She was thrown down with the vehicle as well. She was a very lucky dog...to have survived that wreck."
That part of the interstate has been the site of several such crashes.
LOUIS FOREHAND, WORKS NEARBY "There's been a few of them over the years...cars coming down on their tops ...it's a pretty wild place to watch the interstate."
No more information has been released on the cause of the crash, or the names of the two who were hurt.
