Carolina Crossroads:
I-20/26/126 Corridor Improvement Project
Phase 3 - I-20/26 & I-26/126 System Interchanges, St. Andrews Road at I-26 Interchange, and Bush River Road at I-20 Interchange
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 www.SCDOTcarolinacrossroads.com.
In general, Phase 3 consists of reconstruction of the I-20/I-26 system interchange, reconstruction of the I-26/I-126 system interchange, reconstruction of the I-26/St. Andrews Road interchange, reconstruction of the I-20/Bush River Road interchange, completion of widening of I-20 west of the I-20/I-26 interchange and widening of I-26 from just west of St. Andrews Road to the US-378 interchange.
