Both are nice but I think I prefer the other. To me fog evokes a feeling of cool and smooth which I think you accomplished with the other one and its cool tones and smooth look to the fog where this has warm tones and an edgier feel to it. Now if you were going for an aged look here I think you succeeded.
Real tough choice, but I think I prefer this one. It has a real 1930's feel to it. The cars are discreet enough so it could well be the 30's when the bridge first opened.
