Alpine is a modern facility, built around 2000. It was expanded to include a few remote drill sites a few miles away.
In addition to being the 3rd largest producing area on the North Slope, it was a "proving ground" for how compact a commercial facility could be built. It was intend as typcial of facilities that could be done in ANWR.
Alpiine is not connected by road to other North Slope production facilities. It is separated from the by the Colville River. Every winter, they build an ice road crossing this river typically rated to carry 100 ton loads.
Note, the lines on the map above show fields and pipelines. Roads are not shown.
Below is CD4, on of the remote drill sites added to the Alpine unit.
So the construction takes place in winter on an ice road that melts when summer comes, hence the roadless facility?
