Firstly, thanks go to everyone who helped us with the task.
I've used your first FRM ColJack, I've had it tailored a bit to span the canyon more accurately, but now it fits.
Here's the FRM:

I'm having some problems, though. How to put it in a map?
I'va added it to the SCENERY.LST as the last item, I've put it in the scenery pallete on the mapper (clicking EDIT on the last, blank item, choosing the FRM , setting material to wood and naming it) ant I put it on the map ( a modified version of the arbridge.map)
When I put the scenery there (covering the original bridge tiles, bridge wall removed) the bridge sits there exactly.
When I exit the mapper and try to reload, I get an "error loading objects" message. It persists until I add the scenery back to the palette manually.
If I exit the mapper and try to load the map into the game, I get a blank map, nothing whatsoever (as if the game moved me to a different elevation. I'm positive the starting hex is set though. Could this be the issue?)
I can't explore the map until I load the mapper again, and remove the new bridge scenery. After that, the map is loadable and back to it's original state.
What to do?
I'm running the mapper with an 1.00 unpatched version of Fallout2.
