SCDOT will open the new Columbia Avenue overpass and ramps at Exit 91 on Interstate 26 on Tuesday, July 12, weather permitting. The new alignment of Columbia Avenue will be the only way to cross over I-26 at this location.
Businesses on the old Columbia Avenue will still be accessible, and the old Columbia Avenue overpass bridge will be closed for demolition. The ramps shown in orange will be opened in a future phase of the project. SCDOT reminds the public to use caution while driving through work zones.
This construction is a part of the Midlands Connection Project, which will improve a 16-mile segment of the Interstate 26 roadway system that stretches from Exit 85 in Little Mountain to Exit 101 in Irmo. The Midlands Connection Project will widen the I-26 roadway, modify three interchanges, and replace seven overpass bridges along the Interstate 26 travel corridor.
The primary purpose of the Midlands Connection Project is to provide more capacity and allow vehicles using this section of I-26 to travel more freely with less congestion when the project is completed and into the future.
