We went under this bridge. The bridge tender guy said that it was 52' high. Our mast is 48', so he said we "should be able to make it"... When we went under it, it was terrifying! You look straight up at our mast as see the bridge ahead way below the top of the mast! It isn't until you actually go under the bridge that you could tell you were going to make it. The funny thing is that there were a bunch of mast head lights and antennas stuck to the side of the bridge where sailboats had hit it!
