Collie Lake King Road SLK 90 – 94 Westbound Climbing Lane

Westbound traffic on Collie Lake King Road, west of Darkan, is often impeded by slow moving heavy vehicles that lose acceleration traversing a 4% incline between SLK 93.5 to 91.9. At the crest, heavy vehicles are often doing less than 20 km/h. This creates a potential safety hazard as inadequate sight distances make it unsafe for light vehicles to overtake heavy vehicles. Twelve years of data show that between the towns of Collie and Lake King, crashes have resulted in one fatality, two hospital admissions and two requiring medical attention. The construction of a west-bound climbing (passing) lane will improve the flow of traffic and reduce the risk of traffic crashes from unsafe overtaking attempts.
