Like A Bridge In Troubled

After browsing a score or 5 of pictures of old stone bridges, work has begun on a 40/54mm compatible toy bridge. 

Just fits in the 4" grid, is wide enough for a wagon, and crosses the masking tape river nicely,  hmm...hope it fits over the painted river, must check that before going farther. The angle of the top rail needs to broaden out a bit I think, or even be flattened though the straight line with an angle seems to be common in low lying areas as does the more difficult curved profile.

Still, its a beginning.
