Authorities have reopened all but one exit lane on Ga. 400 North following a serious injury crash and fuel leak Thursday morning, police said.

Sandy Springs police and fire are still working to clear the accident at the Abernathy Road exit. The off-ramp is blocked for traffic exiting the freeway east toward Dunwoody, police spokesman Sgt. Sam Worsham told AJC.com.

"That's where those lanes ramp from I-285 onto (Ga.) 400 North," WSB 24-hour Traffic Center reporter Mark Arum said. "Big outbound delays on 400 up through Sandy Springs."

A pickup truck was rear-ended by a tractor-trailer, Worsham said. A driver was pulled from the crumpled wreckage and taken to a hospital.

Fuel was leaking from the tractor-trailer onto the roadway, which delayed the crash cleanup, he said.

The crash has “single-handedly affected three interstates pretty severely,” traffic reporter Ashley Frasca said. Both directions on Ga. 400, I-85 and the entire Top End Perimeter are jammed.

Drivers can take Roswell Road to avoid the mess, the Traffic Center reported.
