FRIDAY PHOTO: SNOOPING UNDER BRIDGESPreserve Infrastructure, by Catherine Higgins.
Workers use a bridge inspection truck with an articulating arm. Sometimes called a “snooper,” The hydraulic arm of the truck reaches under bridges so inspectors can take a closer look, and also lets inspectors work from either side of the bridge.
See more bridge inspection photos on UDOT’s Flickr photo stream.
