Traffic Control Plans in Charleston, SC
Traffic control plans for lane and street closures in the City of Charleston and on SCDOT roads in the Lowcountry.
Plans for work in Charleston
LADMA Traffic Control draws traffic control plans for contractors, utilities and property owners working in Charleston. We cover lane and shoulder closures, sidewalk closures with pedestrian detours, full road closures with detours, and utility and fiber work.
You send the location and the scope. We draw the plan to the standards the reviewing agency uses and deliver it as a PDF you can attach to your permit application.
In the City of Charleston, any lane closure in the right of way must be approved by the Department of Traffic and Transportation. State roads also need an SCDOT encroachment permit.

Local rules to plan around
- The City does not accept hand-drawn traffic control plans, and gives no final approval until the plan is approved.
- Residents must be notified at least three days before the permit start date, and at least a week ahead for major projects.
- Construction traffic must stay off residential streets unless there is no other route.
Office names, forms and lead times change. Confirm the current rules with the agency before you apply.
