Bought a MTH **** Gate Bridge that would not fit on my layout because of its footprint several years ago. Sat in a box until a few weeks ago. I rebuilt a table to have an angled side which widened the distance between the two sides to find enough room. The top base of the table is six and a half inches below the track on the table so that the bridge is level with the tracks.
I have learned a lot building it. The **** Gate bridge is just large enough to be cumbersome. I decided against a lift bridge as it would be stressed each time it was lifted or lowered.
There have been many small steps, but tonight, I finally put the hinge on the swinging door base for the bridge. The plan was that the whole bridge support swings out so there is room to get into the center of the layout, but not to be so big that the door to the train room can't close.
It still needs a lot of work to finesse the tracks so they align when it closes without any dip. This picture was just to see if it fit and was relatively level with the tables. I will take it back out and install better bracing, support, install a floor below the bridge, make it look like water below the bridge, and wired.
I am limited in the fact that I have no carpentry skills and have been learning on the go. Here is a picture of the work in progress.
