Need some advice on best glue to use...I built a Walthers steel truss bridge and tied to attach the Walthers bridge track with CA. It didn’t hold. What do you use to glue the track to the bridge?

Most flex track uses a type of Delrin* or "slippery engineering plastic" as the M-R editors call it.
It is a little stringy but several dabs of Walthers Goo has worked well for me. There are other types of contact cements, too, but Goo is a pretty good choice.
* POM or polyoxymethylene
Good Luck, Ed
Thank you. I will try that.
I used gelled contact cement for all of my bridges. However, regardless of the type of glue you use, it helps if you first use sandpaper to scuff the bottom of the ties.
Use a brush to apply the glue to both mating surfaces, then allow it to dry for at least the amount of time specified on the container. If there are no alignment references cast into the bridge deck, place a piece of waxed paper on the bridge deck to allow you to line things up to your satisfaction, then, starting at one end, begin to slide the waxed paper from beneath the ties. Follow along with your free hand, pressing the track onto the deck as the paper is withdrawn - the bond will be instantaneous and permanent.

I just secured the track to the roadbed really well either side of the bridge and it floats on the bridge. It does not appear to move at all when a train goes over. It is a curve on a grade to boot. I let my turnouts float and have not had a problem so I thought I would do the same with the bridge track, so far so good.

Thank you Wayne. You give great advice on this forum and I will say I have used a lot of your suggestions to others. Much appreciate you sharing your knowledge and experience!
