Weekly Poll (5)


Michigan Department of Transportation has recently adopted the use of unmanned, remote-control boats for conducting bridge inspections. Do you think the safer, less labor-intensive technology will become favorable by other DOTs for bridge inspections?


Earlier this month, crews began dismantling the Herbert C. Bonner Bridge (located in the Oregon Inlet of North Carolina) with guillotine-like saw blades in order to use concrete portions for an existing offshore artificial reef. Slated to be complete by 2020, do you think this method of removing the bridge’s piles and spans will prove to be financially effective?


The Mackinac Bridge, located at the Straits of Mackinac in northern Michigan recently received a new paint job with help from a Ruby+Associates-designed movable scaffolding system. Without the innovative equipment, do you think the project would have been able to reach completion within a year?


Last month, Egyptian President Abdel Fattah al-Sisi opened what is being touted as the world’s widest suspension bridge in the world. With six lanes of traffic running in each direction, the Rod al-Farag Axis Bridge is intended to shift traffic, ultimately decreasing travel time around Cairo and on various highways. Do you believe other major cities could benefit from this type of massive infrastructure?


In a recent report conducted by the American Road & Transportation Builders Association, just over 47,000 bridges in the United States are classified as structurally deficient or in poor condition. However, the rate at which these bridges are improved is at its lowest point since the Association began monitoring the data. Why do you believe this might be?
