The Interstate 10 (I-10)/Perryville Interchange, in Maricopa County, Arizona, has been named the Number Three Road in North America by Roads & Bridges magazine.
An Arizona Department of Transportation (ADOT) designated Key Commerce Corridor, I-10 is a critical component to ADOT’s goal to enhance and maintain access to 16 million consumers in Southern California and 13 million consumers in Central Texas. For the I-10/Perryville Road Traffic Interchange (TI) project, ADOT requested that the restrictions of I-10 during construction be minimized, as the 2009 Average Daily Traffic (ADT) count totaled 68,500 vehicles – 27,000 of which are trucks, many which carry goods to and from the Port of Long Beach in California. According to logistics industry metrics there is an $800,000 economic impact for every hour a truck is delayed from reaching its distribution point.
The design-build team consisted of Skanska, Gannett Fleming, Point Engineers, Southwest Traffic Engineering, and Harrington Planning & Design. They took on the challenge, and developed an innovative maintenance of traffic plan to keep I-10 open during the widening and resurfacing of one-mile of the existing I-10 to accommodate four new ramps, the replacement of a one-span bridge with a two-span bridge, and reconstruction of 1,700 feet of Perryville Road from a two-lane roadway to a divided four-lane roadway, all under busy I-10 traffic.
“The I-10 Perryville Traffic Interchange was aggressively paced, but our team was up to the challenge,” said John Derr, PE, a Gannett Fleming executive vice president and West Regional director. “The project required extensive coordination among the design team, design reviewers, construction team, inspection team, third party utilities, local agencies, and other stakeholders. The open communication ultimately led to the project being completed within schedule and to stakeholder satisfaction.”
“Not only were we able to provide an excellent transportation solution to our client, ADOT, but the added-value of securing this award on their behalf is just one of the ways we go above and beyond for our clients,” said Karen Hobbs, PE, highways practice manager in Arizona for Gannett Fleming.
Roads & Bridges' Top 10 Roads awards, created in 2000, recognize the top projects in North America. Each year, nominations are submitted to the R&B editorial staff, which determines the Top 10 list based on project challenges, impact to region and scope of work.
