Project Description
NicNevol supported FDOT District Two in the rehabilitation of SR 5 (US 1), a vital north–south corridor in St. Johns County. The project limits extended from the Flagler County Line to SR 206, covering approximately 7.4 miles of roadway.
Work included milling existing asphalt (¾ in. to 5 ¼ in.) and placing new asphalt layers consisting of Superpave structural courses (PG 76-22) and an FC-5 friction course for improved skid resistance and durability. A stress-absorbing membrane (SAM) layer was applied in designated areas to enhance pavement performance and reduce reflective cracking.
Additional scope comprised base work and stabilization, shoulder treatment, driveway reconstruction, guardrail upgrades, drainage improvements with new culverts and mitered end sections, and rehabilitation of bridge deck expansion joints. MOT included CMS boards, radar speed display units, and business signage to maintain safe mobility through construction. The corridor now offers improved ride quality, enhanced safety features, and a stronger pavement structure designed for long-term service.
