Construction has commenced on Phase 2 of the city of Charleston's Septima Clark Drainage and Transportation Improvement Project.
Several road closures were necessary due to the project. They began this week and it is estimated the roads will remain closed until mid-August. Those closures are:
- The Sheppard Street off-ramp from U.S.-17 will be closed while a 125-foot deep drilled drop shaft is installed. Sheppard Street will be closed from Highway 17/Crosstown to Rutledge Avenue.
- The intersection of President and Fishburne streets will be closed for utility work.
During Phase 2, drainage and road work will be conducted on parts of Spring Street and Cannon Street. This work will begin at the Septima Clark Parkway and continue to Lockwood Boulevard; President Street from Cannon Street to Fishburne Street; Fishburne Street from President Street to Ashley Avenue; and Ashley Avenue from Fishburne Street to Sumter Street.
Planned stormwater infrastructure will include the installation of more than 12,000 linear feet of new stormwater pipe ranging in size from 15 to 54 inches; more than 300 new stormwater structures; the cleaning of more than 10,000 linear feet of stormwater pipes already in use and eight vertical drilled drop shafts that will connect to the deep tunnel system once construction is complete.
Phase 2 will also include landscaping of the area between Spring and Cannon streets as well as water and wastewater improvements and asphalt milling, paving and striping.
Phase 1 of the project, which included construction of vehicular and pedestrian improvements to the Septima Clark Parkway from Coming Street to Spring Street and along nearby side streets as well as the installation of an Intelligent Traffic System. Water and wastewater improvements were also done, as were major drainage improvements.
A $10 million TIGER 1 grant funded Phase 1 of the project. Phase 2, which will cost an estimated $23.5 million, will be funded by the Federal Match Program administered by the South Carolina Department of Transportation.
