On May 1, 2017, the agency overhauled its bus network, the first redesign since COTA's establishment in 1971. The effort simplified routes, increased bus frequency, connected more locations, and reduced bus congestion in downtown Columbus. The redesign doubled the agency's number of frequent lines (from four to eight) and significantly increased weekend service. The project caused a 3.6 percent increase in ridership by May 2018. In August 2017, COTA became the third large transit agency with fleet-wide passenger WiFi. On June 1, 2018, COTA began the C-Pass program, giving employees of certain companies downtown free rides on COTA buses. By 2019, the program enrolled about 420 companies. C-Pass is scheduled to be discontinued on December 31, 2020; property owners will decide whether to fund the program further.
