About Us

Our History

Georgia Bridge and Concrete, LLC traces its origin to Michael G. Williams and Sunbelt Structures, Inc.  Michael founded Sunbelt Structures, Inc. in April of 1985 as a small concrete bridge, culvert and wall subcontractor based in Tucker, Georgia. This new firm primarily focused on work for the Georgia Department of Transportation, local counties and municipalities.  Sunbelt Structures, Inc. began business with two used cranes, two construction crews, and an office staff comprised of two employees.

From these humble beginnings in 1985, the firm enjoyed one success after another and by 1992 was awarded its first major GDOT project as the Prime Contractor. This project was for construction of a critical portion of the University Parkway four-lane divided highway from U.S. 78 into Athens, Georgia.  Upon the successful completion of the University Parkway project, the firm was awarded many more major DOT projects as Prime Contractor.  Some of these were the Sugarloaf Parkway Interchange at I-85 in Gwinnett County; Old Peachtree Road at I-85 in Gwinnett County; the West Cobb Loop, a twin mile long bridge project in Cobb County; and the firm’s largest single project contract for the widening and reconstruction of Highway 441 from Tallulah to Clayton, Georgia valued at over $80 million.

While enjoying the success of managing and constructing major DOT projects as a Prime Contractor, the firm also stayed close to its roots and continued to perform box culvert, wall, and bridge subcontract work for the firm’s major contractor clients and project owners. One such project was the poured in place concrete box culvert under Atlanta’s Hartsfield-Jackson International Airport’s 5th runway.

In addition to self-perform construction services, the firm also enjoyed success in the Construction Management at Risk arena for several prominent private developers beginning in the early 2000’s.  Examples include the Princeton Lakes mixed use development in East Point, Georgia along with the prominent retail redevelopment of Midtown Place along the Atlanta Beltline and adjacent to Ponce City Market in Atlanta, Georgia.

The firm participated in many Design-Build projects over the course of its history including the 5th Street Pedestrian Plaza Bridge Project over the downtown connector at the Georgia Institute of Technology.  Additional Design-Build projects include the new interchange and vehicle bridge over I-85 for the Kia Manufacturing Plant at West Point, Georgia as well as the contract to construct the signature Northside Road Pedestrian Bridge at the new home for the Atlanta Falcons, Mercedes-Benz stadium in downtown, Atlanta.

Over its 30-year history, Sunbelt Structures, Inc. successfully completed well over $1 billion in construction contracts. Then in 2015, Sunbelt Structures, Inc. was acquired by George P. Flanigan, owner of the multifaceted highway construction enterprise, G.P.’s Enterprises, Inc., to forge a synergy between the two firms. The newly acquired firm was renamed Georgia Bridge and Concrete, LLC.

Today, Georgia Bridge and Concrete, LLC operates as an independent company based in Tucker, Georgia and provides the same great products and services it always has to state, county and local governments as well as major contractors, private developers and project owners. It can also leverage the additional resources and capabilities of G.P.’s Enterprises, Inc., when clients need those broader capabilities. Either way, Georgia Bridge and Concrete, LLC is well positioned to move into the next generation of civil-highway construction in the State of Georgia and the Southeast.
