The road to annex (別館への道) is a room on the Island.
This road supposedly heading toward Annex. This road also connects into the shipyard.
In this area, Ashley will drive a huge vehicle where Leon will try to provide cover from waves of armed Ganados militia. An opposing truck will also appear behind you attempting to ram Leon off the road. In order to stop this, shoot the truck until it bursts into flame where it will stop temporary, before attempting again to ram your truck again.
On the way, Leon will have to leave the truck temporarily to push a lever, starting an industrial lift to continue the journey toward the annex. Another truck will appear, this time in front of you, and must be shot in the same way. The truck will force yours to collide with the Antechamber.
