Why is WSDOT installing cable guardrail?
We install cable guardrail because it helps keep motorists safe. Severe injuries and fatalities often result when a vehicle crosses the median and collides with oncoming traffic. We install barriers in highway medians to help prevent injuries and save lives. Before installing barrier in medians, our engineers carefully consider whether barrier would enhance safety, and if so, which type of barrier would work best for each location. They consider a wide array of factors: • accident trends and history • community and driver comments • traffic speeds and volume • road grade, angle and curve • available median and shoulder space • slope of the median • barrier characteristics • installation and maintenance costs We use three general types of highway barrier: cable, guardrail and concrete. All of these barriers are designed to protect drivers, though they do so in different ways. All of our newly-installed barriers must meet federal and state guidelines. The End Result Cable median barrier
