The exit ramp from I-85 northbound to Jimmy Carter Boulevard was shut down Thursday afternoon because of a chemical spill, police said.

“A driver on 85 north called police due to a liquid leaking onto his car from a tractor-trailer,” Gwinnett police Cpl. Jake Smith said in an e-mail. “Both vehicles pulled onto the ramp.”

Smith said police, fire and hazmat units were on the scene at 12:30 p.m. assessing the situation. He did not have an estimate on when the ramp would reopen.

Gwinnett fire Capt. Tommy Rutledge said at 1 p.m. that the incident involved a tanker truck leaking industrial soap. The leak had been stopped, and firefighters were waiting for a crew from a commercial clean-up company to arrive.

He said that two civilians and a police officer were exposed to the chemical, but were evaluated at the scene and did not require transport to a hospital.
