Absolutely, Clark! Thank you for the explanation.

Dylan, that's a broad topic but to start off, this is a "pin connected" bridge. Members are almost all held together by large pins which allow joints to flex freely. This removes most of the bending load on members, most of which are in tension only. Calculation of forces is much simpler. Later bridges used rigid connections where all the members were joined by being riveted to a "gusset" plate. This made a connection that flexed much less, placing a bending load on the various members, requiring them to be able to resist more than just tension. Enough?

I'm trying to learn a little more about the various nuts and bolts of bridges like these. Would someone be willing to explain what's going in some of the joints like these. Thanks!

This bridge is currently impassable, with VDOT closure signs blocking access. It is not readily apparent what the issue might be. That said, there is evidence that traffic of some sort has been circumventing the barricades - possibly farm equipment or 4-wheelers?
