Georgia Department of Transportation in the US is set to invest $113m in new road improvement projects across the state.

Work includes the $56m, 30-mile rehabilitation of Interstate Highway 16 (I-16) near Dublin in central Georgia, along with resurfacing roads and entrance and exit ramps between State Route 26 in Laurens County and State Route 29 in Treutlen County.

The I-16 project, awarded to US-based APAC-Tennessee, is expected to be completed by the end of July 2015.

Transportation Board chairman, Johnny Floyd, said that the state has to properly maintain assets such as I-16, as well as investing in new technologies and approaches to improve mobility.

Further new projects include the $2.49m resurfacing and rehabilitation of 3.8 miles of State Route 10 in Clarke County from the SR 10 Loop to Minor Street, which was awarded to CW Matthews Contracting and is scheduled to be completed by 30 September 2013.

GDOT will also invest in the installation of electronic variable speed limit (VSL) signage on the northern portion of Interstate Highway 285 around Atlanta to enhance mobility and improve safety.

"The I-16 project, awarded to US-based APAC-Tennessee, is expected to be completed by the end of July 2015."

Brooks-Berry-Haynie & Associates of Georgia received the $4.9m contract to install the VSL signage and supporting fibre optics along the 36-mile stretch, which will be completed in late 2014.

In addition to improving safety, studies have shown that VSLs allow motorists to arrive at destinations faster, even when travelling at a reduced speed.

The department plans to widen 22 miles of State Route 35 between Colquitt and Tift counties to make space for turn lanes with an investment of $17.2m.

GDOT will also spend $7.5m on resurfacing 16 miles of State Route 1 in Decatur County.
