SAI celebrates National Rollercoaster Day – August 16th – and all of the structural and civil engineers (and rollercoaster design requires many) who make the thrill possible. As you ride the twists and turns of your local rollercoaster (and a shoutout to Kennywood in Pittsburgh), you can thank the many engineers who make the ride safe, fun, and wild. #rollercoasterday #nationalrollercoasterday
