Swain's Cut Bridge, Road bridge over Intracoastal Waterway in Oak Island, North Carolina, United States

Swain's Cut Bridge carries NC 906 over the Atlantic Intracoastal Waterway, linking Oak Island to the mainland. Its 980-foot deck is 80 feet wide, with four traffic lanes on prestressed concrete girders crossing 65 feet above Mean High Water. The high-rise design spans a narrow part of the channel with only three main spans.

The bridge was constructed by the North Carolina Department of Transportation and opened to public use in 2010. It was built as part of the island's efforts to improve infrastructure and provide better connections to the mainland.

The bridge takes its name from the Swain family, who owned land in the area when the Intracoastal Waterway was developed in the 1930s. Today, the structure stands as a reminder of the families whose property shaped the island's development.

As a second crossing to the island, this bridge provides an important route for daily traffic and storm evacuation routes. The wide four-lane roadway allows for reasonably smooth traffic flow, particularly during off-peak hours.

The bridge serves as a critical evacuation route during hurricanes, making it an essential safety feature beyond everyday traffic. Its elevated roadway was specifically designed to remain passable even under extreme weather conditions.
