SCDOT announces completion of the Harden Street and South Main Street Projects in Columbia

Columbia, S.C. (July 10, 2025) - The South Carolina Department of Transportation has announced the completion of two projects in Columbia. The Harden Street and South Main Street projects were two projects that aimed to enhance the areas and make the roadways safer.

The South Main Street Project, adjacent to the State House, now includes a dedicated cycle lane, landscaping, added street lighting, new crosswalks and more visible pavement markings. These safety improvements will keep drivers and pedestrians and cyclists safer when traveling through the area.

The Harden Street Project also focused on safety improvements including reducing travel lanes which is a traffic calming measure that also reduces distance pedestrians have to cross. Flashing yellow arrows allow drivers to make left-hand turns after yielding to oncoming traffic, reducing the time spent sitting at lights. Landscaped medians added in the project enhance the natural beauty of the area and encourage pedestrians to use dedicated crosswalks, enhancing safety.

Secretary of Transportation Justin Powell said, "These two projects are examples of the work we are doing at SCDOT to enhance mobility and revitalize our roadways. Safety is our number one priority and we are happy to announce the completion of these two projects that showcase our dedication to keep road users safe."

SCDOT held a walking tour today to celebrate the completion of the projects.
