The photograph on the left features a tractor trailer on top of a bridge with a large concrete structure on the bed of the truck. The words “Oversize Load” appear on a sign on the back of the trailer, and orange flags appear on the concrete structure and on the truck. A worker wearing an orange and yellow safety vest appears in the lower right portion of the photograph. The photograph on the right shows a two lane bridge. There is a tractor trailer in the left lane. No traffic appears in the right lane. A sign appears to the right of the right lane. The sign reads "Weight Limit Reduced - Any Single Axle - 20,000 LBS - Any Tandem Axle - 34,000 LBS - Max Gross Weight - 80,000 LBS - Legal Axle Weights Only"

Thank You!

This slide shows a black-and-white image of a bridge deck with four lanes. The two left lanes (in the direction of traffic) show vehicles, and the two right lanes are closed and workers are taking measurements with hand-held nondestructive evaluation tools. The lanes with traffic and the lanes with workers are separated by a traffic cone. The lanes with workers have white dots on a 2-foot by 2-foot grid painted on the top of the concrete bridge deck.
