This design-build project involved the widening, elevating, and upgrading of an eight-mile stretch of I-95 to provide additional capacity and enhanced resilience to the 100-year storm. Notable project highlights included widening the roadway from four to eight lanes from US 74 (Exit 13) to south of US 301 (Exit 22), 250,000SF of retaining walls to raise I-95 above the Lumber River 100-year flood elevation levels, “top-down” construction techniques at the Lumber River bridges to mitigate environmental impacts and to optimize the construction schedule, reconstructing three interchanges (exits 17, 19, and 20) with new bridges and ramps to modern design standards, replacing dual bridges over the Lumber River and over CSX Railroad, and construction of two triple-barrel box culverts.
ICE served as the Lead Design Firm responsible for design project management, structures design, roadway design, hydraulic/hydrological design, geotechnical engineering, utility and railroad coordination, traffic engineering, and FAA and airport coordination.
