The history of TANK is that of an agency at the center of the Northern Kentucky community, serving the public transportation needs of Boone, Campbell and Kenton counties and downtown Cincinnati for more than 30 years. It's roots go back to 1971 and the Greenline, a private transportation company that served Northern Kentucky announces that operations will cease. In 1972, voters in Kenton and Campbell counties and the City of Florence voted to approve general obligation bonds to continue mass transit services. TANK has been growing and serving the region ever since.
