News Summary

The South Carolina Department of Transportation has announced a major traffic shift at the Old Wire Road and U.S. 21 intersection in Lexington County.

Drivers are advised to slow down, adhere to road signs, and remain patient throughout the construction process, which is set for completion by spring 2026.

Lexington County Traffic Shift Planned at Old Wire Road and US 21

The South Carolina Department of Transportation (SCDOT) will implement a significant traffic shift at the intersection of Old Wire Road and U.S. 21 in Lexington County starting on Monday, October 13. The current 4-way stop will transition to a roundabout configuration, aiming to improve traffic flow and enhance safety for drivers and pedestrians.

As the SCDOT prepares for this transition, drivers are urged to slow down and pay close attention to posted signs and the directions from crew members in the area. Warning signs have already been installed to alert drivers of the upcoming changes.

Details of the Transition

Once the traffic has been redirected to the new roundabout layout, SCDOT crews will proceed with the removal of temporary pavement located in the center of the roundabout. This crucial step will facilitate the construction of the center island, which enhances the functionality and aesthetics of the roundabout.

After the center island is completed, final paving and pavement markings will be conducted to ensure a clear and safe driving environment. The overall construction project, which encompasses these modifications, is expected to reach completion by spring 2026.

Importance of the Change

The shift from a 4-way stop to a roundabout is part of a broader initiative by SCDOT aimed at improving traffic management in busy areas. Roundabouts have been shown to reduce the likelihood of severe accidents and can lead to smoother transitions for vehicles. The implementation in Lexington County is expected to have similar benefits, enhancing both safety and efficiency for drivers in the region.

Throughout the construction process, SCDOT appreciates the patience and understanding of the public. These changes, although temporary, are essential for the long-term improvement of local traffic conditions.

Background on the Project

The move to install a roundabout at this intersection is a proactive measure taken by SCDOT in response to growing traffic volumes and the need for improved control at this intersection. By replacing the existing 4-way stop, which can often lead to delays and potential accidents, the new design aims to streamline traffic flow while maintaining safety for all road users.

Moreover, the installation of a roundabout aligns with contemporary traffic engineering standards that favor circular intersections for their efficiency. Given the expected growth in traffic and development in Lexington County, such upgrades are seen as vital to keeping pace with demand.

Stay Informed

Drivers are encouraged to stay updated on the progress of the construction and any further changes that may arise during this period. Adhering to road signs and guidance from SCDOT crews can ensure a smoother transition for everyone involved.
