On August 4, 2025, the Federal Highway Administration (FHWA) awarded $86.3 million to the South Carolina Department of Transportation (SCDOT) under the Highway Planning and Construction program (CFDA 20.205). This formula grant funds Phase 3C of the Carolina Crossroads I-20/I-26/I-126 Corridor Improvement Project, a design-build construction contract for interstate highway improvements and critical bridge replacements in South Carolina. The project specifically encompasses I-20 improvements and the replacement of the Saluda River and CSX bridges as components of the broader multi-phase corridor enhancement initiative.

The award supports highway construction, preservation, and infrastructure improvements consistent with the Highway Planning and Construction program's authorization under the Infrastructure Investment and Jobs Act. As the primary state transportation authority, SCDOT administers federal highway funding for major transportation infrastructure projects across South Carolina, utilizing this award to deliver essential improvements to interstate connectivity and bridge infrastructure that support regional transportation networks and economic activity.
