By the 1950s, the Grace Bridge‘s narrow two-way lanes no longer served the growing area. A new three lane bridge without dips and curves opened next to the old bridge in 1966 and was named for Silas N. Pearman, chief commissioner of the state highway department. The region’s continued growth made the existing bridges obsolete, and the eight lane Arthur Ravenel, Jr. Bridge opened on July 16, 2005.
