The highway is frequently used here escpecially after Caine takes over the power plant. Lana, Quinn, Cookie and Albert go through the highway in order to get to the desert and Hermit Jim's shack. Brianna and Jack also use it for Brianna to race a bullet at the beginning of the book.
In Fear Sam, Dekka, and Jack are travelling through the highway to the beach to look for the missiles which dropped onto the beach at the end of Plague.
Outside the barrier on the highway a camp has been set for the families of the people which is guarded 24/7 by the army.
