I downloaded the " <kuid:86105:38001> Steel Girder Bridge " from DLS, and it only needs the " <kuid:86105:38003> Bridge Track " as a dependency.
Installed in Trainz 2022, they don't present any errors, just warnings, since they are old objects from Build 1.3, and I can use the bridge without any problems.
According to the header of your question, you downloaded the bridge from a site considered a pirate site in this forum because they host Trainz content without permission. Perhaps the person who hosted the bridge on that site manipulated it and changed the track type it needs, and that's possibly why you're having problems.
My advice is to delete that bridge from your Trainz and download the bridge again through DLS.
