29 Jun Project Updates: June 2022
Rogers Bridge (Duluth, GA): A milestone was achieved this month as the main truss of Rogers Bridge was installed over the Chattahoochee River. The individual members of the 228-foot long truss were prefabricated and installed on-site over two weeks. The 110-year old bridge over the Chattahoochee River was redesigned and reimagined as a pedestrian pathway that will allow for the free flow of cyclists and pedestrians to and from north Fulton County, south Forsyth County, and western Gwinnett County. T&H’s Buford office, provided project management, land surveying, transportation engineering, hydrology & hydraulics, utility coordination, and water main design for the overhaul of the bridge.

The expansion of the WWTP from 5.85 MGD to 9.0 MGD with nutrient removal process with an anaerobic basin, new five-stage oxidation basin, post aeration, two new 120’ diameter clarifiers, tertiary filters, and centrifuge dewatering was designed by Thomas & Hutton for the Town of Smyrna.
The existing components are being upgraded as well, such as headworks with new screens, raw water pumps and VFDs, existing oxidation ditches retrofitted for a three-stage advanced process, and UV disinfection upgrades.
Forest Acres Drainage Phase 2 (Charleston, SC): Forest Acres Drainage Improvements Phase 2 rolling along in Charleston. Improvements to the Forest Acres and 5th Ave drainage basins in West Ashley intended to alleviate recurring drainage and flooding issues including severe roadway and flooding of residences and businesses.
