I made a trestle bridge and it worked out pretty well except that it did not hold up to the stress of my trains going over it. It got some movement near the top by the track so I would make sure that it is checked out a few times to be sure it is secured after you start using it. I finally took mine off and made a bridge with fake cement securing it. But I would use a trestle again sometime because they look so great with a train going over it. My problem could have been faulty construction or wrong glue or something. I have seen many on layouts that last forever. I think if you could use a few tiny brads here and there in the framework to help secure it would look authentic and be stronger.
