HOLDEN BEACH BRIDGE
Holden Beach, North Carolina
Bridge
on NC 130 over the Intracoastal Waterway.
The
1,800-foot long, high-level, fixed structure consists of 20 approach spans of
Type III & IV prestressed concrete AASHTO girders and 3 channel spans of
prestressed, precast box girders. The
channel span lengths are 86 feet, 117 feet and 100 feet.
This bridge structure features compound curvature in horizontal alignment in order to accommodate rigorous geometrical constraints imposed by Intracoastal Waterway vertical clearance and alignment on existing NC 130. The vertical geometry consists of both crest and sag vertical curvature and varying superelevation.
Channel bents were designed with an integral fender system.
