Lewisville residents voted in a special election held on September 13, 2003, to become a full member of the Denton County Transportation Authority (DCTA). The authority began running a regional bus service in November 2006. In 2011, the Old Town, Hebron, and Highland Village/Lewisville Lake stations opened as commuter stops along the route of the DCTA's A-train. The route continues north to Denton and south to Trinity Mills Station in Carrollton, where it connects with the Dallas Area Rapid Transit (DART) Green Line to Dallas. DCTA also owns a Rail Operation and Maintenance Facility in Lewisville.
