Climbing and Passing Lane Prioritization Study

Climbing and Passing Lane Prioritization Study

Completed 2015 - Passing and climbing lanes provide additional lanes for vehicles to safely pass other vehicles while maintaining speeds. Implementing passing and climbing lane projects provides traffic operational and safety benefits at a cost that is far less than fully widening a highway. In an effort to enhance safety and mobility on Arizona's roadways, the ADOT worked on updating the 2003 Passing and Climbing Lanes Prioritization Study. This update further refines the identification and prioritization methodology previously utilized and develops a prioritized list of candidate locations that would provide the most benefit to the traveling public.
