COLUMBIA, S.C. — Construction work commenced Monday to remove and replace several boardwalk sections at Congaree National Park.

Located in central South Carolina, Congaree National Park spans 26,692 acres and is home to the largest remaining tract of old-growth bottomland hardwood forest in the southeastern United States.

Sections B, D, and F of the boardwalk have surpassed their intended service life and are due for replacement. The project is expected to take around 18 months, with completion projected for summer 2026.

During the construction, various boardwalk sections will be closed on a rotating basis, starting with sections B and C, with detours provided. A portion of section B, which is low to the ground, will be removed and replaced with a new elevated structure.

Meanwhile, section C will close temporarily to allow crews access to the work area. Sims Trail will be used for transporting materials and equipment in and out of the area. Although some trails will remain open, park officials urge hikers to stay aware of equipment and adhere to all marked closures.

Closure work for sections D and F will begin in the coming months.
