WALKER — Both lanes of Interstate 12 eastbound just west of Walker are open now, according to the Walker Police Department.

Two lanes of the interstate were closed earlier due to an overturned 18-wheeler. The road is expected to be clear by 5 p.m., according to an email from State Police.

The contents of the trailer will have to be offloaded by hand before the 18-wheeler can be removed, said Walker Police Capt. John Sharp.

The lane will be closed for several hours. The closure is expected to cause lengthy delays on eastbound I-12 throughout the afternoon and evening, Sharp said.

Motorists are advised to use alternate routes, including U.S. 190.
