TriCounty Link Transit Study The TriCounty Link (TCL) transit system provides fixed, commuter, and on-demand transit services to the rural residents of Berkeley, Charleston, and Dorchester counties. TCL is developing a transit study to plan for more efficient, effective, and convenient service for the entire TriCounty Link area, including specific recommendations for the fast-growing Summerville area. This project is led by the Berkeley-Charleston-Dorchester Council of Governments (BCDCOG), which operates TriCounty Link service.
