Route description

The Ōita Airport Road begins at a signaled intersection with Japan National Route 213 just to the east of central Hiji. From there it briefly travels north to meet its spur route, a route that links it to the Hiji Bypass. When the routes merge, they turn to the northeast, traveling out of Hiji and in to Kitsuki. The road curves more to the east in Kitsuki and then enters the southern part of Kunisaki. It ends in Kunisaki upon meeting Route 213 once again.

History

The Ōita Airport Road opened on 25 November 1991. A spur route of the toll road, connecting it to the Hiji Bypass, was opened on 30 March 2002. Tolls were removed from the road on 1 December 2010.^[2] Many sections of the road have been widened from two lanes to four since its opening.^[3]
