[1] Part of State Route 49, it leaves the Warrego Highway at Dalby and runs for over 290 km until it reaches St George.

It is also on the shortest route to St George and Cunnamulla from any locality on or near the Queensland coast from Bundaberg to Coolangatta.

After about 7.8 km it crosses Myall Creek just south of its junction with the Condamine River.

It runs through rich farming land until it reaches the locality of Kumbarilla near the intersection with the Surat Developmental Road.

The road then passes by and through the Kumbarilla State Forest, an area of about 86,000 hectares[3] of native bushland.
