rave: Grady's Valentine to Cable-Stayed Bridges
Sunday, February 23rd, 2025 03:48 pmGrady Hillhouse, PE is a civil engineer who’s expanded that professional credential into a media empire:
I look forward to his 20-minute videos twice a month at PracticalEngineeringChannel. He explains crucial infrastructure—water and sewage systems, power distribution grids, transportation—with luscious stock footage and homey see-through models he cobbles together in his garage.
I strongly recommend his Valentine’s Day contribution: An Engineer’s Love Letter to Cable-Stayed Bridges

I agree that cable-stayed bridges are exquisitely beautiful—they bring the gracious sweep of sailboats back to our bodies of water. Their simple central towers hold a fan of cables to suspend the roadway. As Grady explains, they’re faster and cheaper to build as well as easier to maintain.
Grady doesn’t go into the history, which begins centuries ago and accelerates in the past 50 years. Thanks to excellent PR, I assumed they were originated by Spanish architect-engineer Santiago Calatrava. Close to home, he used similar technology on the 2001 extension to the Milwaukee Art Museum. This STRUCTURE magazine article explains how wrong I was--they cite 1615 for the first cable-stayed bridge!
Have you seen a cable-stayed bridge? Is there another infrastructural design that makes you grin?
