Dorchester Road Widening — $181M Plan to Ease Traffic

Dorchester County officials have unveiled plans to widen about 5.6 miles of Dorchester Road into a six-lane corridor, with public input shaping alternatives, sound barriers, and traffic flow.

In Dorchester County, SC, officials have unveiled plans to widen about 5.6 miles of Dorchester Road (from Old Trolley Road to the Charleston County line) into a six-lane corridor. A public meeting drew strong community interest. The project price tag is $181 million, funded in part by a transportation tax referendum that residents overwhelmingly approved in 2022. Interchange alternatives (including a flyover near Oakbrook), sound barriers, and public traffic flow concerns are all part of the conversation. Construction isn’t expected to start until 2029, and a second community meeting is scheduled for Spring 2026.

How It Relates to Your Property

Major road widening of this scale can affect your home in multiple ways: higher traffic/road noise, changes in access routes, possible property acquisition for right-of-way, and effects on resale value. By understanding when and where these changes are coming, you can plan for potential disruptions or make decisions about your property with more confidence.
