Not convinced the park bridge needs all that prefab steel
They're putting up that walking bridge over in Riverside with sections made in a shop. Folks act like factory pieces are always stronger, but watching it go together, the field connections seem like a weak spot. What's wrong with trusting a crew to fit and bolt on site?

Shop welds beat field bolts any day.

Aren't we making too big a deal? Plenty of bridges built on site with bolts have lasted decades. Look at the old railroad trestles, they're still standing. Sure, shop welds are neat, but field crews know what they're doing. Is a perfect factory weld always better than a good field fit? Sometimes the worry is just for show.
