I added the clear plastic guard walls to the bridge sides, another hobo at the campfire, and a track worker on the bridge walkway. The only job left for the gate is to move the magnetic lock on the bridge end due to the extra width of the clear plastic wall. I can then go back to laying track up to and away from the bridge/gate.
I am putting the finishing touches on my bridge-gate and can soon move on to laying more track. The hobo at the wood fire was a nice idea. I also ballasted the bridge ends and added the walkways. I may put a track worker on one of the walkways. I am still trying to decide if I will need horizontal adjustment of the gate for temperature or humidity changes in the future.
