The new 0.9-mile Intracoastal Waterway Bridge is a significant benefit to the local community, serving as a critical link for vehicular and pedestrian traffic, emergency access, and hurricane evacuations between Topsail Island and the mainland.
The new bridge replaced the previous steel truss swing-span bridge that was constructed in 1954. The vertical clearance of the new fixed-span, 65-foot high rise structure allows commercial and private vessels to freely pass under the bridge, eliminating wait times and improving both waterway and roadway safety.
The Intracoastal Waterway Bridge is nearly 4,000-LF long and 53-feet wide with two vehicular travel lanes, a bike lane, and 10-foot multi-use path. New roundabouts on each end of the bridge provide more adaptive traffic flow patterns. The new bridge was constructed from a temporary work bridge installed from either side of the Intracoastal Waterway. This effective use of construction phasing allowed the channel to remain open during construction and enabled the contractor to complete the project nearly a year ahead of schedule.
SEPI is proud to have provided construction engineering and inspection services for the new bridge structure and associated roadway improvements including material sampling and testing, document control, and contract administration along with roadway grading, paving, and drainage operations.
