PNA-484-12182025DB SR 25 at Darien River Bridge Replacement

The Georgia Department of Transportation (GDOT) is procuring design-build services through a Two-Phase Best Value selection method for the SR 25 at Darien River Bridge Replacement project located in Long County, Georgia. The procurement seeks a Design-Builder team composed of a Lead Contractor and Lead Design Consultant to design and construct a new bridge approximately 1,441 feet long and 55 feet wide, offset 40 feet west of the existing alignment along SR 25/US 17/SR 99/N. Walton Street at the Darien River. Key deliverables include the complete design and construction of the bridge structure while maintaining two-lane, two-way traffic during construction through phased implementation—initially constructing a portion of the new bridge, shifting traffic to it, demolishing the old bridge, and completing the remaining span. The project corridor covers approximately 0.5 mile and includes a shared-use path and sidewalk as integral components. The Design-Builder team must include personnel prequalified by Georgia DOT with the Lead Design Consultant holding minimum prequalification in Major Bridge Design and the team collectively prequalified in disciplines including NEPA documentation, ecology, archaeology, hydraulics, surveying, utility coordination, and erosion control. Phase 1 requires submission of Statements of Qualifications (SOQ) by December 26, 2025, with up to five finalists selected by April 22, 2026; Phase 2 involves proposal submission by August 27, 2026, and price proposal opening on September 18, 2026. The selection committee will evaluate proposers based on Lead Project Manager qualifications and experience, key personnel credentials with demonstrated familiarity with Georgia DOT-specific processes, minimum ten years of experience delivering similar projects, and apparent suitability for the project type, with final award determination based on the highest combined score of price and technical proposals per Georgia's Design-Build Procedures regulations. An Industry Forum virtual presentation is scheduled for January 14, 2026, followed by optional one-on-one meetings on January 15, 2026, and the Request for Qualifications will be issued on February 19, 2026.
