It must be about six years ago that the parallel taxiway was half finished before the funds ran out.
Until the requirement for a 180 at the end is removed by the finishing of the taxiway there will always be the odd "error". As long as it is accepted by the appropriate management and not blamed on the crew there is no problem.
I remember one of our 777 training captains knocking a lamppost over at Grenada with his wingtip. Bit embarrassing but that's all.
Most of these Caribbean airfields were designed for Dakotas and apart from the runways being extended not a lot of the other facilities have been enlarged... enough said.
