Pittman Construction Co. of Conyers, Ga., has been awarded the contract for a new interchange at Interstate 20 and Three Points Road.
Terrell McMillan of the Georgia Department of Transportation said the contract was awarded for $8,058,774.36 with a completion target of Jan. 31, 2013.
McMillan could not say when construction on the interchange would begin.
He said Pittman had submitted a notice of intent to discharge stormwater at the site and DOT is awaiting word from the state Environmental Protection Division.
DOT spokeswoman Cissy McNure said in April that the project, with an original cost estimate of more than $11 million, could begin in July and construction could take about two years.
The interchange will certainly benefit the county, McDuffie County Commission Chairman Charlie Newton Jr. said then.
"We can make it an interstate-access industrial park. That's very valuable to these large industries," he said.
The project also will allow large trucks to circumvent downtown Thomson and have direct access to the interstate, Newton said.
