The Don N. Holt Bridge is a parallel chord, three-span continuous, modified Warren-type truss bridge that carries Interstate 526 (I-526) over the Cooper River between Charleston and North Charleston. It was built in 1992 by the South Carolina Department of Transportation and was designed by HNTB Corporation.
The bridge provides a connection between the communities east of the Cooper River, including Mount Pleasant and Daniel Island, to North Charleston and I-26. It is part of a major hurricane evacuation route for the area.
The Don Holt Bridge is adjacent to a Kapstone (formerly MeadWestvaco) paper mill.
The bridge was named for Don N. Holt who served in the South Carolina House of Representatives and was in the insurance business.
