Hi Bob,
From my research the walkways were originally designed for crews and if the bridge was within range of a turnout for the obvious reasons, cutting cars and the like. The placement of the bridge on the layout is not within range of a turnout in our simulation. Furthermore a walkway encourages trespassing and walking the span. It was decided to drop the walkway assembly as it was easily removed and I suspect intentionally left that way for this reason from MS models Korea. I think the bridge will look far better without the walkway as most of the bridges I've seen in this design don't have them any longer and this holds true into my era of modeling the 1940's and 50's. Thank you for asking Bob I really appreciate the comment.
Erik
