The projects cost $51 million and span Georgia, from metro Atlanta to Washington County.
They include a $14.4 million project to build auxiliary lanes along a busy Macon highway and $10.1 million to refurbish a stretch of Interstate 85 from Franklin County to the South Carolina border.
Another $9 million will be spent to replace and refurbish bridges in Coffee County, Colquitt County, DeKalb County and Douglas County. Some $7.6 million will improve a main road in DeKalb County.
Mr. Perdue said the state is "using these federal dollars wisely to improve our transportation network and to put Georgians to work."
