Thanks for your design! We like what you did with the bridge and how you put it so beautifully into an emblem. After looking at some of the other logos, we decided that an emblem is probably going to be too "busy" for us (too many small elements), because you won't be able to see it well if it's small.
We like your design sense, though, so we hope you stay in the tournament.
We like #70 and #46 the best so far. You can really tell exactly which bridge each one is! We like what you did with the background in #72 also. Could you add some kind of background to #70 and #46 to make the bridge stand out? We will need it to stand out more so that it is clearly visible on our sign.
Also, We like all caps in the name as in #70, but could you try a font with a little less white space?
