Sundt Construction, Inc. and joint venture partner Vastco recently completed the State Route 260 widening improvements between Cottonwood and Camp Verde west of Interstate 17 in Arizona.

The project expanded eight miles of two-lane road into a four-lane divided highway. It also includes a new bridge and a multi-modal pathway from Cherry Creek Road to Interstate 17, as well as seven roundabouts. The full-access roundabout intersections were constructed at Thousand Trails Road, Coury Drive, Cherry Creek Road, Horseshoe Bend Drive, Wilshire Drive and two new locations to accommodate projected future traffic demands in the Verde Valley.

“With the Verde Valley’s recent growth, this key stretch of State Route 260 had become too congested,” said Sundt’s Senior Project Manager Eric Weston. “With the changes made driving conditions will improve for those traveling on this stretch.” 

The job also involved Sundt’s first use of Intelligent Compaction (IC) methods, using integrated measuring, reporting, and GPS systems installed on vibratory rollers. This technology allows operators to monitor compaction in real-time, leading to more uniform and longer-lasting pavement.
