A wreck involving two trucks temporarily blocked all lanes of I-285 westbound at Chamblee Dunwoody Road/N. Shallowford (Exit 30) in DeKalb County on Wednesday night.

All lanes were reopened by 9 p.m., but the area remained congested. Motorists were advised to use an alternate route to avoid extended delays, the Georgia Department of Transportation said.

As authorities worked to clear the scene, traffic was diverted to Peachtree Industrial Boulevard.

No information on injuries was immediately available.
