List of COTA routes and services

[4] The Central Ohio Transit Authority operates multiple services without fixed routes.

COTA Plus, stylized as COTA//PLUS, is a microtransit service in Grove City and northeast Franklin County.

C-Pass holders, university students, children, and those with discount IDs receive free or reduced fares relative to their eligibility for other COTA services.

The agency began other circulators, including Easton, Broad Street, and Westerville services around 2000.

Previously, the agency offered a similar service with a $5 fare from 2001 to 2003, cut due to low ridership.

The redesign doubled the agency's number of frequent lines and significantly increased weekend service.

[60] In 2019, COTA ended its OSUAir service that connected Ohio State University directly with the Columbus airport, citing low ridership amid other bus route options.
