There are no detailed maps of Cuba, except the Atlas de Cuba which dates back to 1978. This atlas is not available anymore. (I obtaiond it at second-hand at the Havanna open-air book market). This atlas gives a very detailed view of Cuba 25 years ago, including the location of the sugar mills and railways. I have scanned a selection of pages from this atlas. By 2005 the road system as shown on these maps is virtually unchanged, apart from some new highways.
ATTENTION: The maps are up to 300kB each!
