Darien Bridge Project
From the Georgia Department of Transportation:
The existing bridge over the Darien River needs to be replaced as it does not meet current design standards and has observed deterioration in the structure. The project proposes to replace the SR 25 (US HWY 17) bridge over Darien River in McIntosh County using innovative Design-Build delivery method.
This project will replace the existing bridge on State Route (SR) 25 over the Darien River in McIntosh County, Georgia. The existing bridge was built in 1944 and does not meet current design standards. The existing bridge is structurally deficient and has observed conditions of deterioration in the structure.
The new bridge structure at SR 25 over the Darien River will include a shared-use path and sidewalk. The profile of the replacement bridge will be adjusted slightly to accommodate the required vertical clearance.
Benefits of replacing the bridge at SR 25 (US 17) over the Darien River include:
- Improves safety for motorists as the new bridge will meet current design standards
- Accommodates bicyclists and pedestrians with multiuse, shared path and sidewalk
- Construction of a platform as requested by the community to perform the city of Darien’s annual Blessing of the Fleet
After careful consideration, Georgia DOT is shifting the delivery model of the SR 25 bridge at Darien River from the traditional Design-Bid-Build (DBB) to innovative Design-Build (DB) to expedite the replacement of this bridge. The DB delivery method selects one entity under a single contract to provide design and construction services and allows for overlapping design and construction activities. With a DB delivery method, Georgia DOT can leverage industry and construction partners to bring creative solutions and innovation to help reduce construction duration, maximize the use of resources, minimizes potential impacts to the traveling public, and potentially lower the project cost.
The project team will be coordinating with stakeholders on the change in delivery method being used for this bridge replacement project and a proposed detour. Georgia DOT plans to host another Public Information Open House (PIOH) in Q3 2022 to share more information about the project design, proposed detour, and schedule.
More information will be shared in the coming months as the project advances.
