Preconstruction north view, circa 1949-50, from the hill shows only one home, and, to the right, one pole with electrical wires along Moraga Avenue. The large eucolyptus tree in the center of the image, at the intersection of Florence Avenue with the right-of-way, will serve as a marker.

Turning to the southeast prior to construction, circa 1949-50, a truck on Moraga Avenue has just passed the barely visible SN Thornhill Drive trestle. The remainder of Moraga Avenue is still obscured below the homes on the eastern flank above central Montclair.

With more of the hill removed, the graded portion of the future freeway south of Moraga Avenue can be appreciated in this northeast view, circa 1951. Although often linked with the first phase of the MBF, this section did not open to traffic until completion of the second phase in Oct. 1956. A more detailed view follows.

Images such as this circa 1956 southeast view showing the potential of the SN to bring all traffic to a halt should also remind us that Moraga Avenue was a barrier to freeway traffic well into 1963, or 6 years after abandonment of the SN right-of-way. More on this subject soon.
