CHUBBUCK — The Chubbuck Road Interchange reconstruction over Interstate 86, the state’s first Diverging Diamond Interchange design, was named western regional winner of the America’s Transportation Award in the “Under Budget, Small Project” category at the Western Association of State Highway and Transportation Officials 2014 conference in Albuquerque, N.M. The region includes 15 western states.

It was a record-breaking year for the America’s Transportation Awards, as more state DOTs than ever participated, entering more projects than ever before with 73.

The Chubbuck interchange was completed last year on a highly compressed time schedule in nine months and was $2.1 million under the budgeted amount.

“Idaho is honored to receive the transportation award in the Under Budget, Small Project category,” said Idaho Transportation Department Director Brian Ness. “Good things like this happen when you hire good employees and then get out of the way so they can unleash their creativity and ingenuity.”

The winning interchange is located at the crossing of Interstate 84 and U.S. 91 on the Yellowstone Highway. The original interchange could not accommodate oversized shipments from several major businesses in the popular shopping and dining area.

With the original interchange at the end of its service life, ITD designed a unique new interchange to accommodate these massive, oversized loads.

The interchange also provides significant economic benefits to the city of Chubbuck and local businesses, and will accommodate higher volumes of traffic in the future.

According to the Idaho Department of Transportation, the exchange improves the quality of life for local residents by providing wide bicycle and pedestrian paths with signalized crossings and pedestrian-actuated, rapid flashing beacons to warn drivers of pedestrian presence.

Fast-tracked construction began in March 2013, and was completed in November 2013, at a total construction cost of $10.8 million.
