Overview
ITD has been monitoring SH-11 near milepost 2.5 on the Greer Grade and repairing areas where the roadway has settled. Recent monitoring has shown increased movement in the hillside, prompting a more extensive stabilization project to protect the highway and keep it safe for travelers.
Construction
Crews will construct a soil nail wall—a retaining wall anchored into the hillside along the downhill side of the highway—to help hold the soil in place. Crews will also remove a portion of the existing roadway bed and replace it with material that allows water to drain more easily.
Travel impacts
Starting at the beginning of Oct., SH-11 will be reduced to one lane through the project area and a temporary traffic signal will operate 24 hours a day.
- Travelers should expect delays of up to 15 minutes.
- One lane will remain open for all traffic, including commercial vehicles.
- Travelers may use an alternate route to avoid delays.
Construction is anticipated to continue through mid-February. The schedule is dependent on weather and site conditions and may change.
