The westbound lanes of Ga. 316 in Gwinnett County have reopened, some two hours after a logging truck overturned and shut down the major thoroughfare.

According to the state Department of Transportation, two trucks and a smaller vehicle crashed just before 6 a.m. at the junction of Ga. 316 and Ga. 20 near Lawrenceville.

One of the trucks overturned, losing its load of logs, the DOT said.

Three people were injured, according to authorities.

Gwinnett fire Lt. Colin Rhoden said that when firefighters arrived, they began treating those injured, and putting down material to absorb hydraulic fuel that was leaking from one of the vehicles.

Rhoden said crews were able to absorb the hydraulic fuel before it could get into storm drains.

Rhoden did not know the extent of the injuries.

All lanes of Ga. 316 in both directions were blocked, as was Ga. 20.

The eastbound lanes of Ga. 316 had reopened by 7 a.m., and the westbound lanes were reopened about an hour later, but traffic was still slow through the intersection as crews worked to remove the remaining wreckage.

Another multi-vehicle wreck in DeKalb County had most southbound lanes of I-285 blocked before daybreak Tuesday.

That wreck happened about 5:30 a.m. near Northlake Parkway when a huge bale of cardboard fell from a truck and was hit by other vehicles.

DOT spokeswoman Chata Spikes said two vehicles were involved in the wreck, and that there were injuries reported.

Four southbound lanes of I-285 remained blocked just before 6:30 a.m., with traffic squeezing by in one right lane. Those lanes reopened around 7 a.m.
