I'll agree with everyone else on the given selection here. As for how I try to decide: Ideally, you'd have the history of 'what came first'. Whichever level this one is at goes as the 'baselevel'. Either a new road / railway / .. goes: OVER it, making that a bridge UNDER it, making it a tunnel AT THE ORIGINAL LEVEL, making the existing road/path a bridge or tunnel based on how that got adjusted.
That makes this a railway-bridge: https://www.google.be/maps/@50.9501557,3.1304248,3a,60y,255.18h,91.97t/data=!3m6!1e1!3m4!1sV8dGdG1hKMYxX3JldKdTSA!2e0!7i13312!8i6656 But this, just a bit further, and at the same level as the road shown in the previous example, a tunnel for cyclists: https://www.google.be/maps/@50.9516067,3.1299799,3a,48.9y,281.94h,86.62t/data=!3m6!1e1!3m4!1sPooi08Nvz-feFB6XzaibnQ!2e0!7i13312!8i6656 Hope that makes sense, I personally feel it matches with how people tend to label things.
