Norm, that looks awesome. Especially good job minimizing the visual impact of the wires from the signal heads. Here's a couple in-process shots of a similar one I am making. I snipped out the vertical supports an installed sway bracing. Dave did the painting and weathering for me. With the PRR-22 and -42 signal heads, there are a lot of wires to bundle and route through the truss, so I have a lot of work to do to make them blend into the structure better.
By the way, I believe that signal bridge at Glenfield was accidentally hit by an MOW crane, hence the replacement in 2015.
