Nathan has a shot of the top of the shoe of one through truss and the roller nest of the other through truss atop one of the lally columns that has some cracking in the concrete and perhaps a little loose iron wrapping.

Looks like solid concrete underneath...So it shouldn't cause a problem. If it had been gravel filled that would be a different story!

Funny that I didn't see that don about the center lalley column being ripped open like that.Makes one wonder how that affects the structural integrity of the bridge.Maybe someone knows.

Neat bridge; hope that center pier holds up.

I've never seen lally columns peeled open like that.
