Welcome to Roadscapes Wednesday, each week this post will talk about roads and infrastructure related topics. I am called the “road geek” for a good reason, I love roads and love talking about roads!
In May of 2021, inspectors on the I-40 Mississippi River Bridge near Memphis, Tennessee discovered a major crack in a structural member. They immediately contacted emergency managers to shut down this key crossing to vehicle traffic above and maritime traffic below. This video from Practical Engineering provides a summary of the event, including a discussion on arch bridges, fatigue in steel members, and national bridge inspection standards.
