Don N. Holt Bridge, Road truss bridge in Charleston, United States
The Don N. Holt Bridge is a road bridge that spans the Cooper River with three continuous sections and carries Interstate 526 between Charleston and North Charleston. The structure has six traffic lanes, measures 93 feet (28 meters) wide, and provides 155 feet (47 meters) of clearance for vessels passing underneath.
The bridge opened in 1992, completed by the South Carolina Department of Transportation to replace the older Arno Richardson Bridge as the main crossing. The project was part of broader infrastructure efforts to improve traffic flow between the two cities.
The bridge carries the name of a South Carolina politician who served in state government. It represents modern infrastructure that shaped how the region developed and connects its communities.
The bridge experiences heavy traffic daily, especially during peak hours when congestion is common. Those interested in the structure should note it is primarily designed for vehicle use and not pedestrian crossing.
The bridge features a pavement lighting system that activates during dense fog to guide drivers safely across. This weather-responsive technology helps manage visibility on one of the region's busiest crossings.
