Diving knowledge:
SR400 Peach Partners will design, build, finance and operate the corridor. The three-party consortium used a joint venture of Atlanta-based FlatironDragados and Madrid-based Acciona Construction to manage the design and construction, according to a statement sent to Construction Dive from the Georgia DOT.
The states are rolling public-private collaborations to finance the development of expensive infrastructure. Ferrovial, the Amsterdam-based civil engineering company, recently won P3 work in Texas, Virginia and North Carolina, said Silvia Ruiz, global head of investor relations. The Georgia DOT expects the P3 model to reduce the funding needed and speed up delivery.
Infrastructure work, especially roads and bridges, continues to drive overall construction growth in the US, even as other non-residential sectors face faltering demand.
For example, construction of highways and bridges begins rose more than 85.2% month over month in December, according to the Dodge Construction Network. The momentum of the sector fell start in 2026although it remains positive compared to the same period last year, according to Dodge’s breakthrough data.
