Crawlerway
From Kerbal Space Program Wiki
The Crawlerway is a location or "micro biome" in the KSC situated directly in between the VAB and the Launchpad. Like all location in the KSC it is its own biome with research from this area yielding the same amount of science per biome for any other KSC building, and only exist on the ground. Hovering even a meter above it will give flying over Kerbin's shores data. It can not be entered unlike other building and as of the current game is only a cosmetic feature, with no direct impact on gameplay. It can not be destroyed.
