The Birdsville Developmental Road (State Route 14) is a mostly unsealed road in south-west Queensland that branches off the Diamantina Developmental Road at a point 103 km west of Windorah and runs to Birdsville. Its length is 273 km. The road crosses a major channel of the Diamantina River just before reaching Birdsville. It links with Cordillo Downs road (via Cordillo Downs station) and Arrabury Road (via Haddon Corner), both of which lead to the South Australian town of Innamincka.
