I mean, in principle, it is theoretically possible to build a literal trans-Atlantic physical bridge. Hell, in theory, you could build a bridge that would let you walk all the way to Mars if you really wanted to. The laws of physics allow such things, without impossible materials.
It would really have to be a flexible accordion bridge. The two planets rotate around the sun at different speeds.
Keppler would like a word with you...
You don't know orbital mechanics as well as you think you do! Look up concepts like the orbital ring and launch loops, structures built on the interplay of orbital momentum rather than static material strength. I'm dubious whether there would ever be an economic reason to build a train track all the way to Mars. But from a pure physics perspective, it's entirely possible.
There are more things in Heaven and Earth than are dreamt of in your philosophy.
