Abstract:
Prestressed concrete bridges located in aggressive environments of coastal North Carolina require significant maintenance and often require replacement after as little as 40 years of service. Detours during periods of maintenance or replacement are lengthy in such remote areas, and result in significant disruption and direct/indirect costs to industry and local communities. The Harkers Island Bridge replacement, the first all-FRP reinforced/prestressed concrete bridge in North Carolina, was designed to address the problems associated with corrosion of critical lifeline bridges in coastal areas. Construction on the 28 span, 3,200 ft long, Harkers Island Bridge replacement in Carteret County, North Carolina, began in 2021. The existing bridge opened in 1970 and is the only link to the mainland. The existing bridge had its superstructure replaced in 2013 and is currently categorized as structurally deficient due to deterioration from corrosion of the internal steel reinforcing. This presentation will give an overview of the current state-of-practice on the design of FRP reinforced/prestressed concrete bridges in the United States, and an update on the construction progress of the Harkers Island Bridge replacement project.
