After conducting research, I was unable to find any information about a boat ramp named Landing Road 438 in Baxley, Georgia. It is possible that the name has changed, or the ramp no longer exists. Alternatively, the ramp may be a small, local boat launch that is not well-documented online.

Without more information, it is impossible to determine what kind of boat ramp Landing Road 438 may have been, how wide it was, what body of water it served, or what types of craft were permitted to launch from it.
