On September 20, 2023, a freight train derailed in Yemassee, SC; severely damaging a 1937-era bridge built over three CSX railroad tracks, including an Amtrak line. The Yemassee railroad hub holds historical significance due to its connection with the Marine Corps Air Base and Parris Island. Additionally, the bridge is part of US 17A/21, a crucial hurricane evacuation route and a vital road for the town of Yemassee. The South Carolina Department of Transportation immediately assessed the damage, closed the bridge to traffic, and determined the structure needed replacing. While the railroad quickly performed repairs to make the structure safe for train passage, SCDOT ensured the historic importance of the site was preserved by conducting an archaeological excavation before building a new bridge. The $16 million project replaced a 123-foot-long structure with a new 246-foot structure, built within a year of its original closure, despite challenges like Hurricane Debby and complex demolition work over an active railroad. The entire project was finished ahead of schedule and reopened to the community, including critical functions like emergency services.
