Isis Highway

The Isis Highway is a state highway in southern Queensland, Australia. The highway is relatively short, and runs for 137 km in a north-east / south-west direction between Bundaberg North and the Burnett Highway at Ban Ban Springs. The Isis Highway links the sugar producing Bundaberg and Fraser Coast regions with the cattle farming districts of the North Burnett.

The highway takes its name from the Isis River, which flows between Childers and Burrum Heads. The highway also passes through a significant amount of the former Isis Shire local government area, of which Childers was the administrative centre.

The Isis Highway is signed as State Route 3 between Bundaberg and Childers, and State Route 52 between Childers and Ban Ban Springs. The section between Bundaberg and Childers is a state-controlled regional road (number 19A) while that between Childers and Ban Ban Springs is a state-controlled strategic road (numbers 19B and 19C)

Route description
The road commences at a roundabout in Bundaberg North as State Route 3 and runs south as Hinkler Avenue, crossing the Burnett River on the Don Tallon Bridge. Most of this section is one lane in each direction. After 2.0 km it passes through a five-way intersection, crossing Bourbong Street and turning south-west on Takalvan Street. This four lane road continues for a further 3.3 km to the Airport Drive / Kendalls Road exit, where it becomes Childers Road, reverting to two lanes.

Childers Road passes to the west of Bundaberg Airport and through the outer suburbs of Kensington and Branyan before reaching the village of South Bingera. From there to Apple Tree Creek it passes through a mixture of farm land and forest, with sugar cane and other crops intermixed. Childers Road is 41.8 km in length, making a cumulative distance to the Bruce Highway at Apple Tree Creek of 47.1 km.

From Apple Tree Creek the Isis Highway runs south-east concurrent with the Bruce Highway for 6.4 km to the western outskirts of the town of Childers, where it turns south on Broadhurst Street as State Route 52. The street name is dropped as the road leaves the town, and the two lane road runs south-west and south through farm land and forest for 45.8 km to Biggenden. From Biggenden a further 37.7 km generally south-west through similar country leads to the Burnett Highway at Ban Ban Springs, making a total cumulative distance of 137.0 km.
