Big River Bridge Clearances

[cruiserbill]

Hi all,

I am trying to determine bridge clearances on a few of the big rivers.

Ohio - from Cinci to the Mississippi
Mississippi - From the Ohio to the Tenn Tom and
Tenn Tom to the gulf.

Specifically, would a mast height of 57 feet from the water line clear the bridges on the above sections of rivers, or would it be necessary to demast first.

Thanks!

Can't make it down the Tenn-Tom greater than 52 feet +/-. Tennessee River you will be ok, but will have to scrape your antenna at Kenlake during summer pool. There is a railroad bridge that must be raised at New Johnsonville +/- Mile 100 on the Tennessee. You will have to get mast down by Headwaters of the Tenn-Tom until you get to Mobile. Then you can go GICW to Pensacola. East from Pensacola, Navarre has a 49 foot bridge, so it is outside from Pensacola eastward.
