Arizona DOT adds monitoring technology to state bridges

Arizona Department of Transportation (ADOT) engineers in Phoenix will get real-time information on the conditions of four interstate bridges in remote north-western Arizona thanks to technology funded by a US$768,000 Federal Highway Administration grant. To enhance safety and efficiency, ADOT will use the Accelerated Innovation Deployment Demonstration grant to add structural health monitoring systems to the Interstate 15 bridges, embedding sensors on the superstructures that record, analyze and share da

6576 Arizona Department of Transportation (ADOT) engineers in Phoenix will get real-time information on the conditions of four interstate bridges in remote north-western Arizona thanks to technology funded by a US$768,000 831 Federal Highway Administration grant.

To enhance safety and efficiency, ADOT will use the Accelerated Innovation Deployment Demonstration grant to add structural health monitoring systems to the Interstate 15 bridges, embedding sensors on the superstructures that record, analyze and share data.

The systems, which will be installed by this autumn, will help ADOT identify and address problems quickly and decide when the bridges will need major repairs or replacement. They also will help ADOT engineers determine when to conduct inspections, which are required at least every two years and involve lane restrictions.

“The technology made possible by this grant will enhance the safety of the travelling public and help inform Arizona’s investments along this vital corridor,” ADOT Director John Halikowski said.

    Arizona DOT upgrades camera system
    Arizona’s traffic operations centre was built more than twenty years ago; the first traffic camera was installed over Interstate10 in 1990. That’s all changed now thanks to a recent US$2.1 million upgrade of the camera system by Arizona Department of Transportation (ADOT) which replaced cables with fibre optic lines, so the cameras now show fresh images every ten seconds rather than every five minutes. The upgrade has also replaced the 32 video screens in the traffic operations centre, enabling staff to sca

    Remote remedies help US authorities identify bridge deficiencies
    Every day 185 million vehicles – cars, trucks, school buses, emergency response units - cross one or more of America’s 55,710 'structurally compromised' steel and concrete road bridges, the highest concentration of which are in Iowa (nearly 5,000), Pennsylvania and Oklahoma. Nearly 2,000 of these crossings are located on interstate highways, according to the American Road and Transportation Builders Association's recent analysis of the US Department of Transportation's 2016 National Bridge Inventory.

    In a move to make travel on Interstate 10 safer and more efficient, the transportation leaders of Arizona, Texas, New Mexico and California have created a coalition supporting innovation along the corridor. The I-10 Corridor Coalition is modelled after a coalition involving 15 states that govern Interstate 95 between Florida and Maine. For Arizona, the partnership is designed to remove what transportation officials refer to as ‘friction’, such as the variety of commercial vehicle permitting and inspectio
