What they’re describing is a real phenomenon in the West Bank, though. Not that they necessarily run all of their utilities within/alongside a single road, but that Israeli settlers will strategically isolate Palestinian communities by building infrastructure that separates them.

The basic idea is that settlers will pick an attractive hill to build a settlement. They’ll also build a road leading to just that one settlement, and utilities which supply just that one settlement. Palestinians can’t freely cross Israeli territory, they have to cross through specific checkpoints. So they couldn’t cross the road or access any of those utilities or else risk violence/death.

On one side of the road you might have a small Palestinian farming community, on the other side a larger town that they sell to. With the road, the farmers can no longer transport livestock/produce to the town to sell, and the Israelis just dammed the stream they used for irrigation, too. So the choice becomes either pack up and leave, or die in poverty. The larger community loses a source of food, and if their situation becomes too precarious as a result, they’ll pack up and leave as well.

Then with those communities gone, oh look, more room for settlements.
