This simple over-head sign was designed to fit on the I-48 high sections, though it can easily be used to span any road. The span between the bottom stands on either side is 5″ which should be plenty to span a 2 lane road. The clearance from the table surface to the underside of the top beam is 8″.
It’s not very wide but a miniature on a 30mm base can be placed on top with some of the base over-hanging the edges.
For 28/32mm scale tabletop miniature games
