On 12/4/08, as part of a "Florida Keys Wish List," I posed the following question:

32. Channel Five (near Statute Mile 1150 on the Inside/ICW route) is arguably the most important passage to connect between the Inside/ICW passage and Hawk Channel. That’s partly because it is crossed by a fixed, 65-foot bridge. Conversely, there is a real absence of navigational markers on Channel Five. Has anyone else been bothered by this scarcity of aids to navigation?

Responses follow:

Channel 5 Bridge posed no problems for us in either direction.  We did pass through both times with good daylight.
