Construction to add the first-ever climbing lane to ease traffic flow along a stretch of I-17 south of Camp Verde began in January 2013 and consists of a $11.8 million project adding a third traffic lane in two different areas along southbound I-17 to help move traffic climbing along Copper Canyon Hill near Camp Verde (mileposts 280 through 287).
One additional lane has been built between the State Route 260 and General Crook Trail traffic interchanges to allow larger vehicles to gain speed before merging while also providing more room for passenger vehicles traveling past slower traffic. Crews also will build a two-mile long climbing lane to improve traffic flow to the top of Copper Canyon.
The majority of the work will take place behind concrete barrier as crews perform blasting of rock cuts along the roadway. Possible closures of I-17 in both directions will occur overnight between midnight at 3 a.m. Sunday through Thursday nights.
