This interchange is located immediately to the north of the Bruce Highway (M1) diverge where the road continues south as the Gateway Motorway (M1) and the Gympie Arterial Road (A1). The relatively short length of weaving section between the Dohles Rocks Road on ramp and the Gympie Arterial Road (A1) creates a traffic shockwave that extends for several kilometres to the north along the Bruce Highway (M1). This results in major delays and safety hazards on a daily basis, primarily during the morning peak period.
Significant queues and delays also occur along Dohles Rocks Road as vehicles cannot enter the traffic stream on the Bruce Highway. A redesigned interchange is proposed that separates the two southerly traffic movements (Gateway Motorway M1 and Gympie Arterial Road A1) at Dohles Rocks Road before they enter the Bruce Highway preventing the weaving and resulting traffic delays from occurring.
