US 378 Sunset Split

You spoke. We listened!

January 2024 Drone Footage


US 378 (Sunset Boulevard) serves as one of the major arteries into the Town of Lexington and has experienced significant growth over the past several years. Over 50,000 vehicles travel through the intersection of Corley Mill Road and Sunset Boulevard a day, which would be equivalent to the population of the 7th largest city in the state. Additionally, Corley Mill Road provides primary access to River Bluff High School, multiple residential developments, and the Lake Murray Dam. 


The Town of Lexington’s Sunset Split project is the next phase of the Corley Mill Gateway project. The project is a continuation of the recently completed US 378 and Ginny Lane intersection improvements project and the I-20 West Bound Exit Ramp improvement project. The Sunset Split project is funded by the Town of Lexington’s local Hospitality Tax, Corley Mill TIF District, and a proviso in the Fiscal Year 2025 SC State Budget.

Following an August 2020 Virtual Public Information Meeting, which saw approximately 2,800 website visits and 144 comments, the Town of Lexington revised the design to address the comments received.
