Bolton Field (ICAO: KTZR, FAA LID: TZR) is a public airport in Columbus, Franklin County, Ohio, United States.

[2] Bolton Field opened on October 24, 1970, a day after Franklin County Common Pleas Court rejected a move by a nearby private airport (located on Darby Dan Farm) to stop it.

Major Harry Charles Davidson, a WWII veteran residing in Groveport, Ohio, was the first airport manager at Bolton Field.

The airport was built to handle personal and business aviation, freeing Port Columbus for commercial traffic.

[3][4] The airport is home to regular events hosted by the Experimental Aircraft Association's Young Eagles Program.
