The Don N. Holt Bridge is a parallel chord, three-span continuous, modified Warren-type truss bridge that spans 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 Interstate 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.
