In Georgia, a major, multibillion-dollar infrastructure project is underway to reshape State Route 400.
The design and construction team broke ground on the SR 400 Express Lanes project Wednesday, according to an announcement from civil engineering firm ACS Group. The Georgia DOT endeavor will change about 16 miles of the highway, increase capacity and add express lanes. Total investment on the project is $10.8 billion, according to the announcement. Construction costs amount to $4.6 billion, according to FlatironDragados.
The announcement follows the Georgia DOT’s timeline — in March, the agency announced that construction would begin this month.
Atlanta-based FlatironDragados and Madrid-based Acconia Construction will lead construction. The Georgia DOT selected SR 400 Peach Partners, a JV of ACS Infra, Acconia and French asset manager Meridiam, as the design-builder of the project in a public-private partnership.
The work will stretch from a transit station in Fulton County, Georgia, to McFarland Parkway in Forsyth County, per the announcement. The construction team will create dynamically priced express lanes in each direction along the route.
The builders will also add more connections to the Interstate 285/SR 400 Interchange, a major crossing for commuters and travelers in the Atlanta metro area. Infrastructure builder Ferrovial completed a $690 million contract to add new ramps and lanes to the interchange in 2025.
Alongside the connections, the team will add new bridges and corridor-wide technology systems designed to optimize traffic flow and improve safety, per the announcement.
A loan from the Transportation Infrastructure Finance and Innovation Act, which provides credit assistance to significant infrastructure projects around the country and can finance up to 49% of eligible project costs, will fund construction, along with tax-exempt private activity bonds, according to the announcement.
The SR 400 work is a key part of Georgia’s Major Mobility Investment Program, which will overhaul transit corridors across the state.
