Main Road Improvement Projects Underway

Posted In Road & Traffic Alerts

Charleston County and the South Carolina Department of Transportation (SCDOT) began Main Road Improvements project yesterday. Citizens can expect to see nighttime lane closures during the two week operation, weather permitting. The purpose of the project is to improve travel at Main Road and U.S. 17 (Savannah Highway) and raise portions of Main Road to alleviate potential flooding. Nighttime lane closures on Main Road between the Limehouse Bridge and U.S. 17, will occur 9 p.m. to 6 a.m. beginning Sunday night Nov. 1. The lane closures are expected to last two weeks.

As of Nov. 3, project improvements unrelated to resurfacing have been postponed due to weather and are scheduled to resume the week of Nov. 9.

Project improvement includes:

  • Widening of the road, six feet on each side, from the railroad overpass to approximately Morse Avenue. This additional width will allow for an additional lane off of Johns Island to be established with traffic barrels during an evacuation event.
  • Adding an additional five inches of asphalt between Morse Avenue and Old Charleston Highway (the section of road that recently flooded).
  • Resurfacing a section from the Limehouse Bridge to U.S.17.
    Improvements to the intersection at Old Charleston Highway including:
  • Installation of a right turn lane from Main Road onto Old Charleston Highway headed toward Charleston.
  • Installation of a left turn lane from Main Road onto Old Charleston Highway headed toward Savannah.
  • Installation of a left turn lane from Main Road into the Bojangles driveway.
  • Installation of two concrete islands to establish right turns only from Old Charleston Highway onto Main Road.

The project is funded by the SCDOT and the Charleston County Transportation Sales Tax program. Anyone with questions about the project can call Charleston County’s Transportation Development Department at (843)202-6140.
