The SR400 Express Lanes Project is a transformative $4.6 billion infrastructure initiative led by SR400 Constructors, a 50/50 joint venture between Ferrovial Dragados and ACCIONA. Commissioned by the Georgia Department of Transportation (GDOT) and Georgia State Road and Tollway Authority (SRTA), the project will add two 16-mile express lanes from Sandy Springs MARTA Station (Exit 5) to McFarland (Exit 12), enhancing mobility along one of Georgia’s busiest corridors. With a peak workforce of over 500, the project also includes dedicated bus rapid transit stations and significant improvements to the corridor. Construction began in late 2022, with substantial completion anticipated in 2031.
