DeKalb County commissioners and regional Walmart representatives were scheduled to break ground July 27 on a new supercenter on the site of an old auto dealership in Stone Mountain.

The 150,000-square-foot supercenter near the intersection of Hairston Road and Memorial Drive will employ 250 full-time and part-time associates and will generate an estimated $4.9 million in sales taxes.

Walmart officials said the new supercenter will spur economic development and road improvements. Local charities and organizations also will benefit from its commitment to community and giving initiatives.

Commissioners Sharon Barnes Sutton, Larry Johnson and Stan Watson were scheduled to attend the 11 a.m. ceremony.

Improvements that will accompany the construction of the store include:

n A new traffic signal will be installed at the entrance from North Hairston. A right turn lane will be added on Memorial Drive, and the existing right turn lane from Lauren Parkway onto Memorial will be extended.

n The signals will be interconnected for better function.

n A traffic control island will be constructed on North Hairston to allow Kenilworth traffic to enter and leave but will prohibit traffic from coming into the community after exiting the Walmart parking lot.

n There will be a dedicated truck entrance on Lauren Parkway.
