In the early '70s, Camino de la Reina (running along the north side of the mall) was rerouted, enlarging the rear parking area. This allowed for the first expansion of the mall (in dark gray), This project added an LA-based Bullock's and eleven inline stores. This North Wing addition was completed in 1975.
