Interstate 26

Home » Guides » South Carolina » Interstate 26

Interstate 26 generally stays west of Columbia, serving commuting interests from Irmo to the northwest and south Lexington County.

Interstate 26 angles southeast from Upstate South Carolina to the LowCountry and Atlantic Coastal Plain. The freeway serves Charleston at the eastern terminus, linking it with the capital city and the Greenville/Spartanburg area (in conjunction with Interstate 385). Northward from the Palmetto State, I-26 continues to Hendersonville and Asheville, North Carolina and the Tri-Cities in eastern Tennessee. Outside of the metro areas in South Carolina, I-26 remains rural, generally with four travel lanes.

The first stretch of Interstate 26 opened in 1960.⁵

The "Malfunction Junction" area of St. Andrews was slated for a massive overhaul as part of a $80 million improvement project starting in mid 1988 with right of way acquisition. Proposals outlined two new directional ramps from I-26 to I-20, and a collector distributor roadway system northward from I-126 to the St. Andrews Road interchange along I-26.¹ Funding for this project however never matriculated.

23 years later, studies and designs were again undertaken to address issues at the exchange between I-20 and I-26. Cost for the project were forecast at $400 million in February 2011, but again funding was not secured.³ Eventually branded as Carolina Crossroads, work on a five phase project upgrading portions of I-20, I-26 and I-126 commenced with a ground breaking ceremony held on November 8, 2021. Phase 3, which replaces the cloverleaf at I-20/26 with a systems interchange, is scheduled to run from 2023 to 2027. The fifth phase, which widens I-26 northwest to Broad River Road, may be completed by the end of 2019.

Interstate 26 was expanded to six overall lanes between U.S. 1 and U.S. 378 in Lexington County during a three year construction project by July 1993. Work here cost $12.1 million.²

Exit 102 with S.C. 60 (Lake Murray Boulevard) was upgraded from a half diamond to a six-ramp parclo interchange during work between March 3, 1997⁴ and late 1999. This construction followed an expansion of I-26 from four to six lanes between Harbison Boulevard and U.S. 176 (Ballentine exit) in December 1993.

Montague Avenue meets Interstate 26 just south of the exchange with I-526 in the city of North Charleston. The arterial connects the freeway with a number of shopping centers and an outlet mall. Pictured here is the eight lane overpass above I-26 ahead of the westbound on-ramp.

The westbound entrance ramp for I-26 on Montague Avenue east precedes the intersection with Mall Drive and Goer Street. Goer Street acts as a frontage road for Interstate 26 to the south while Mall Drive encircles the Charles Towne Square retail complex.
This I-26 shield and guide sign assembly was subsequently knocked down and removed.
