Location & Transportation

The three counties that comprise the Tri-County region sit comfortably in the south-central to southeastern portion of South Carolina.

Interstate 26 offers east/west access through each of the counties, coming down from North Carolina and heading into the Charleston area. Interstate 95 jets down through the state and is a main thoroughfare, running through the junction of Dorchester and Orangeburg counties.

Eight U.S. highways (52, 17, 78, 176, 178, 601, 301 and 15) and 14 state highways (6, 27, 33, 41, 45, 61, 165, 311, 642, 314, 210, 310, 267 and 453) offer access throughout the region, too.

The Tri-County region is served by multiple airports. Two airports that are within a one hour’s drive are Columbia Metropolitan and Charleston International airports, which both offer trunk, regional and commuter carriers.

More than 70 flights per day are offered by major airlines such as American, U.S. Air, Delta and United.

Dorchester County Airport in Summerville is a general aviation airport that offers fuel, a lounge for both passengers and pilots and flight training services.

Other airports in and around the area are Summerville Airport, St. George Airport, Lowcountry Regional Airport, Santee Cooper Regional Airport, Berkeley County Airport and Orangeburg Municipal Airport.


For rail transportation, Norfolk Southern in North Charleston and CSX Transportation in Moncks Corner both serve the area.

Ports play a major role on the east coast. With the Tri-County’s proximity to the Atlantic Ocean, the area is no different. The Port of Charleston is heavily relied upon; it’s the number one containerized cargo port on the South Atlantic and Gulf Coasts and fourth largest in the United States. Dorchester County is home to one of the state’s two foreign trade zones.
