One positive method is to position wood blocks to the bridge base falls into the "slot".
I am assuming you are talking about a lift out bridge and not a motorized one. I found this video for a double track lift out bridge...................Paul

Dennis, just in case here is another part ..........Paul
Are you talking about something like this? Put an alignment pin at the end.

Don. That's it. I forgot to mention... It will be hinged. The problem is it dropping into the exact spot every time. It is a truss bridge that spans 3 feet. Looking at yours, I guess I could put 2 tiny cones on the bottom of the bridge so when it comes down to meet the block that would have matching holes. Thoughts?

I took picture before pin but there is no flexing so alignment is good. My friend, whom I built this for, has no complaints.
Line up your track, drill down into support block and put a a nail in the hole.
Table leaf pins.
