Speed limit reduced from 110 km/h to 100 km/h
A ‘real world’ speed assessment was undertaken, coupled with speed data, infringements from Western Australia Police Force and public feedback. Based on this data, the current median operating speed on this stretch of road was found to vary from 99-to-103 km/h.
- As a result, the report “determined that reducing the speed limit until other infrastructure enhancements could be implemented would improve public safety”
- The speed limit change will only increase travel time between Two Rocks Turnoff and Lancelin by an extra three minutes. The 100 km/h speed limit starts at the end of the 90 km/h zone located approximately four km south of Breakwater Drive, and continues until the start of the 90 km/h just south of K.W. Road.
- The speed limit will be reassessed once all recommended infrastructure improvements have been finalised.
Road widening, linemarking and construction of 4 overtaking lanes, with Wide Centre Line Treatment (WCLT) to create more space between opposing traffic providing additional reaction time for motorists.
Installation of curve warning signs, wildlife warning signs and replacement of guide signs.
Installation of edge and centre audible line marking
By providing an audible warning to prompt driver recovery, this treatment has the capacity to reduce head-on crashes as well as single vehicle ‘run-off to the right’ crashes.
Safety barriers installed
Safety barriers were installed between Seabird and Lancelin
