Karrinyup Road/North Beach Road Upgrade

Karrinyup Road /  North Beach Road Intersection Upgrade

 

The upgrade to the busy intersection of Karrinyup Road and North Beach Road, Gwelup, has been completed.

In partnership with DownerMouchel, we engaged a contractor to undertake a range of improvement works at the intersection to significantly improve traffic and pedestrian safety. These works included:

  • Extending the left-turn pocket eastbound along Karrinyup Road;
  • Extending the right-turn pocket westbound along Karrinyup Road;
  • Improved drainage;
  • Improved pedestrian crossings;
  • Traffic signal upgrade;
  • Upgraded lighting; and
  • Resurfacing.

There were also be some modifications to the general layout of the intersection, including the removal of corner islands.

 

Timeframe

The contractor started work in early April 2011 and was finished by June 2011.

In March 2011, preliminary work started to construct a temporary bypass lane along the eastbound median strip. This work was carried out after hours and enabled the contractor to maintain two lanes of traffic eastbound for the duration of the roadworks.

 

Benefits

The aim of the project was to improve safety and traffic flow at the intersection, which previously experienced a high number of right turn and rear end crashes.

Past statistics show that 93 crashes were recorded at the intersection over a five year period. The majority of these were rear end collisions and 19 resulted in casualty injuries, which was significantly higher than the average for Perth's road network.

Extending the turning pockets in both directions have improved their storage capacity and reduced the potential of rear end collisions.

The right turn filter movement from Karrinyup Road westbound into North Beach Road has been removed to ensure motorists can make this turn safely, under a fully protected signal control.

The give way sign for traffic turning left off Karrinyup Road eastbound into North Beach Road has also been replaced with traffic signals to accommodate the improved pedestrian crossing facilities.
