If you didn’t get a chance to drive across Ga. 316 this weekend, things will look a little different on your way into work Monday morning.

Over the weekend, the Georgia Department of Transportation made some big changes to one of the busiest intersections in Gwinnett County.

As part of a long term construction project, the DOT shifted lanes on Ga. 316 at Ga. 20.

"The thru lanes on State Route 316 will be moved to the outside lanes and onto what will eventually be ramps,” said DOT spokeswoman Teri Pope. “They're going to be shifted to the outside so that the thru lanes of 316 can actually be lowered by about 20 feet.”

Because SR 316 runs along the highest ridge in the area, 316 must be lowered.

Pope says pay special attention when driving in this area during the Monday morning rush hour.

"As you're on state route 20 and you need to get to state route 316 you may have to go a little bit further along before turning," says Pope.

Keep in mind traffic signals will also be in new locations beginning on Monday.

The $37.4 million construction project is expected to be complete by December of next year and will include more than two miles of new roadways and two new bridges over Ga. 316.

"The next phase of construction is to begin lowering State Route 316 where the new SR 20 Bridge will be built," says Pope.
