Phase 3C—Replacement of I-20 bridges over the Saluda River and CSX Railroad, and I-20 widening between Exits 61 and 63

The South Carolina Department of Transportation (SCDOT), in cooperation with the Federal Highway Administration (FHWA), is proposing improvements to the interstate corridor of I-20/26/126, including the system interchanges at I-20/I-26 and I-26/I-126 in Lexington and Richland Counties. These improvements are proposed to increase mobility and enhance traffic operations by reducing existing traffic congestion within the I-20/26/126 corridor, while accommodating future traffic needs. The corridor's approximately 14 miles of mainline interstate include I-26 from Exit 101 - Broad River Road (US 176) to east of the Saluda River, I-20 from the west of the Saluda River to west of the Broad River, and I-126 from I-26 to east of the interchange with Colonial Life Boulevard. The project website is at SCDOT Carolina Crossroads.

Phase 3C consists of replacement of the I-20 Bridges over the Saluda River and CSX Railroad and the widening of I-20 between Exits 61 and 63. Widening will be in preparation for the final I-20 corridor widening through the Carolina Crossroads project area once completed by later project phases.
