Seajoy,
We just came through jewfish bridge 3 weeks ago. I think that the chart said that it is 65 feet tall. The water level was 1 foot below the depth marker on the
bumpers at the supports, so we had 66 feet, both directions. There is a blue light hanging down about 4 feet from the bottom in the exact center of the channel under the bridge which lowers your clearance right there. We almost cleaned off the top of the mast on the boat we were on.
