Confusion over truck height may have led to bridge collapse

    

According to the National Transportation Safety Board (NTSB) preliminary report and docket, a driver's confusion over the height of his truck load may have contributed to the collapse of a bridge on Interstate 5 in Mount Vernon, WA. On May 23, 2013 around 7:00 p.m., a portion of the Interstate 5 Bridge collapsed into the Skagit River. Two passenger vehicles that were on the bridge during the collapse plunged into the river, injuring three people.

Immediately prior to the collapse, a truck carrying an oversize load on a flatbed trailer was following a pilot vehicle travelling southbound as it crossed the bridge. A pilot vehicle is used to escort trucks with large or oversize loads by driving in front of the trucks to ensure the road ahead can accommodate them. According to the operator of the pilot vehicle, a clearance pole mounted on the front of her vehicle was set at 16 feet 2 inches. The truck's oversize load height was reported at 15 feet 9 inches.  More 



In the wake of recent off-shore oil spills, and with the growing popularity of "fracking" -- in which water is used to release oil and gas from shale -- there's a need for easy, quick ways to separate oil and water. Now, scientists have developed coatings that could help. A report on the materials, which also could stop surfaces from getting foggy and dirty, appears in ACS Applied Materials & Interfaces.

J.P.S. Badyal and colleagues point out that oil-spill cleanup crews often use absorbents, like clays, straw and wool to sop up oil, but these materials aren't very efficient because they also sop up a lot of water, according to an American Chemical Society (ACS) release.  More

Powered by the 100% electric Z-Force motor, the Zero MMX was developed to meet the requirements of military, law enforcement, and security agencies. After extensive testing, the L.A.P.D. chose Zero Motorcycles for its stealth, low cost of operation, maintenance-free power train, and minimal environmental impact, it says.  More
