UPDATE: The driver of a rig that overturned Monday morning, closing the I-10 eastbound exit ramp at La. 92 in Duson, has been cited in the crash.
Terrance Bogany, 50, of Spring, Texas, was issued a citation for careless operation with an accident.
Duson Police Chief Kip Judice says Bogany was injured in the crash and remains in a local hospital, being treated for those injuries.
DPD's investigation revealed that Bogany attempted to exit the Interstate going more than 70 miles per hour, which is "far too fast" for that exit.
Speed was a factor in the crash, but that exit's design also is out of line with standard Interstate exit ramps, Judice said.
The exit ramp opened at about 1 a.m. Tuesday, police said.
It was closed Monday morning after the tractor-trailer rig overturned and started leaking a chemical.
The rig leaked acrylic acid, police say.
Acute exposure to acrylic acid can cause redness, swelling, and tearing of the eyes, runny nose, scratchy throat, coughing, and difficultly breathing, Duson Police say.
Duson Police and Fire worked with Lafayette Fire Hazardous Materials Unit and Louisiana State Police Haz Mat Units to coordinate a safe transfer of the material and containment of the spill.
