This video for the Massena Lateral Bridge Slide from Iowa DOT shows a very nice 3D rendering of the entire accelerated bridge construction process. They are using a lateral slide method to construct the bridge adjacent to the existing one and then slide it into place within 9 days. From a geotechnical perspective, this bridge will be founded on driven piles, and then pre-cast abutment caps with CMP block-outs will be placed over the piles and the block-outs grouted up. The wingwalls will also be precast with the CMP block-outs and supported on driven piles as well. There will also be a driven pile temporary support structure, and driven piles will be used for the reaction frame to attach the threaded anchor rod used to jack the bridge into place.
There is nothing funny about landslides, particularly when you consider the tremendous loss of life that happens all the time around the world, most recently in Taiwan, China, Sierra Leone and elsewhere.

Its a very amusing video that’s really about journalists and their attempts to get the scoop about a story, not really about landslides at all. Click through for the embedded video. Happy weekend. […]
