This update echoes the U.S. 17/Main Road project on John’s Island, emphasizing congestion relief amid resident frustration over noise and Highway 17 traffic (key route to Charleston or Savannah, GA). Charleston County engineering manager Herbert Nimz highlights progress on road widening, roundabouts, and stormwater upgrades—about 34 months from completion (Fall 2028).
Key Improvements
- Multi-lane roundabout at Main, River, and Chisolm Roads to cut backups.
- Overpass structure via pile driving (base installation).
- Overall goal: Faster flow for daily commuters.
Disruptions and Mitigations
Residents report daily traffic snarls and noise, but the county follows SCDOT rules:
- No daytime lane closures for work.
- Pile driving halted 10 p.m.–6 a.m. (overnight staging continues).
- Good news: Pile driving ends by April.
Nimz stresses patience: “We’re trying to get the job done as fast as possible.”
Ties to Broader Timeline
Matches prior updates—ramp pile driving at 45%, summer earthwork/roundabout ahead, full finish in 2028 with utilities, bridges, and signals.
