Croatan Sound connects Albemarle Sound to the north and Pamlico Sound to the south via a broad channel crossed by two sets of fixed bridges. The older, northernmost span has a vertical clearance of 45ft, and has LONG been the bane of sailors who must use the far more difficult Roanoke Sound – Old House channel to cruise south from the AICW/Albemarle Sound to Pamlico Sound, or the other way around. The southernmost twin Highway 64 bridges feature 66ft of vertical clearance, and one might thing with their installation a few years ago, the older span would have been removed. For whatever reason, this has not come to pass.
There are also no clearance boards on either of the bridges that cross the Croatan Sound.

Note that both the NCDOT and the USCG have been apprised of the missing tide boards in Roanoke Sound and Croatan Sound. See article linked below.
