I sought a definition at Dictionary.com , expecting it to suggest that vehicles or people would be conveyed by a bridge across water or some other gap. I had to scroll pretty far down the page to find this one that actually did:
1. a structure that allows people or vehicles to cross an obstacle such as a river or canal or railway etc.
