Selwyn District continues to grow rapidly. Based on current travel choices, SH1 through Rolleston could increase from around 24,000 to 33,000 vehicles over the next 20 years or so. Even with improvements to public transport we expect traffic will continue to increase.
Traffic volume on the highway is almost at ‘tipping point’. This means even a small amount of extra traffic could trigger very long delays at the Hoskyns Road and Rolleston Drive North signals.
Increasing traffic will make it harder for people to get between Rolleston township and industrial areas, leading to long delays at the signals, rat-running, risk taking and increasing safety issues at uncontrolled intersections.
Also, the high safety risk to people at Hoskyns Road level crossing is unacceptable and needs to be addressed. Because the highway is close to the rail line there are short-stacking issues so longer vehicles are unable to queue safely at the level crossing barrier. This causes queues, delays, and serious safety concerns – approximately 40 near-misses – resulting in KiwiRail restricting freight trains to an inefficient 40km/h. An increase in rail activity is also resulting in more traffic hold-ups at the Hoskyns Road level crossing.
Increasing traffic volumes are also making it difficult for people to safely turn right or cross the state highway at Walkers/Dunns Crossing Roads, Rolleston Drive South, Brookside Road and Tennyson Street. There have already been fatal and serious crashes at these intersections and we want to improve safety to avoid more happening in the future.
