English: Animated GIF of USGS maps of 1953, 1961, 1969, 1974, and 2015, showing the conversion of Oregon Avenue to Oregon Expressway in Palo Alto, California, and its interchange with Alma Street and connection to Page Mill Road. In 1953, Oregon Avenue had a T intersection with Alma Street, while Page Mill Road and California Avenue had level crossings across the Southern Pacific railroad tracks. By 1961, the dog-leg connection between Page Mill Road and Oregon Avenue had been made, but Oregon was still a narrow residential street, which connected to US-101 so it became a very busy route to Stanford and the Stanford Industrial Park. By 1969, the Oregon Expressway had replaced about 90 homes on the south side of Oregon Avenue. By 1974, more ramps were added to the Alma Street interchange. At some point, by 2015, the railroad tracks behind the Sutter Packing Company cannery / Maximart / Fry's building were gone; this was the track that connected the Southern Pacific route that ran along what became Foothill Expressway.
