Historical Tour of old US 99
US 99 – 7th Standard Road
Between Oildale Jct and just north of 7th Standard Road, the 99 freeway takes a slightly different course than the original expressway. As a resuly, a short section of the expressway remains partially intact. From Hwy 65 south to Oildale Junction, the northbound side has been obliterated. North of Hwy 65, however, a large portion remains. This section, from Snow Road to Shafter (Lerdo Highway) was upgraded to an expressway in 1943.
The road, 7th Standard Road, is named as it follows the 7th Standard Parallel from the Mt Diablo Baseline, which is located east of San Francisco and governs land surveying throughout the region.
