Phase 3D—I-26/126 System Interchange Design-Build Project

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 3D consists of the reconstruction of the I-26 at I-126 system interchange including the replacement of bridges within the interchange and the I-26 mainline bridge over the Saluda River. This improvement is in preparation for the I-20 at I-26 system interchange improvement to be completed by later project phases.
