ADOT project rebuilding stretch of I-40 wins national award

Roads & Bridges magazine ranks effort near Williams in its top 10
October 11, 2018

PHOENIX – An Arizona Department of Transportation project that’s rebuilding 5 miles of Interstate 40 near Williams has been ranked in the nation’s top 10 by Roads & Bridges, a construction industry publication.

I-40 Devil Dog-New Pavement With StripingThe many freeze-thaw cycles seen annually in this area, combined with heavy snow, snowplowing and use by a large number of commercial vehicles, had stressed pavement considerably between Williams and Devil Dog Road.

A $34 million project completely removed the existing eastbound roadway and replaced the surface with new concrete pavement, and crews are nearly done with work overlaying the westbound roadway with new concrete pavement.

“We were patching potholes after every winter storm,” said Chad Auker, assistant district engineer for ADOT’s North Central District. “It was a big maintenance issue.”

To accelerate much-needed improvements, ADOT and Gannett Fleming, the design firm for the project, completed design work, which normally takes about a year, in less than three months. And construction has moved rapidly in part because crews are incorporating Portland Cement Concrete Pavement recycled from this stretch.

Using Portland Cement Concrete Pavement as the road surface increases pavement life by up to 60 percent and outlasts asphalt overlays by at least 10 years.

Gannett Fleming made the nomination to Roads & Bridges because of the project’s innovative and sustainable approach. Handling the construction is Fann Contracting Inc.

“It’s much-deserved,” Auker said. “The whole team, from the designers to the development team to the contractor and ADOT construction staff, worked hard. There were a lot of long days and long weeks, and the award is well-deserved for bringing new pavement to the road.”

The reconstruction between Williams and Devil Dog Road is among projects improving 34 miles of I-40 west Flagstaff. Crews also are improving 28 miles of northbound Interstate 17 just south of Flagstaff and reconstructing I-40 bridge decks at the interchange with I-17 in Flagstaff.
