All northbound lanes of I-75 were blocked early Friday by a wreck in Henry County, but traffic is now getting by in the two left lanes.

A tractor-trailer and a car were involved in the crash, which happened around 7 a.m. on I-75 northbound at Ga. 20 near McDonough.

Authorities reopened a couple of lanes just before 8 a.m.

Two people were reported injured in the crash.
