THE PROJECT

Located in a rapidly growing area of the Interstate 26 corridor between US 78 (University Boulevard) and Ashley Phosphate Road, the Palmetto Commerce Interchange project will reduce travel times, improve access options, increase traffic mobility in the I-26/Ashley Phosphate Road area, and provide a more efficient commute. The project is led by Charleston County.

Charleston County will construct the urban diamond interchange design, pictured left.

Construction began August 1, 2023.
The County anticipates substantial completion early in 2026.
