Thanks a lot , I appreciate very much these posts , since I worked there in 1973 for 9 months , doing some surveying works for future roads .
To reach some geodesic points we had to walk a couple of miles on a track I would say about 25 miles north of Spanish Town , thru some tunnels and there was also a nice multiple arches bridge somewhere in the mountain .
Very interesting , hope they will revive some parts of it if not all .
Your posts are always interesting !!!
