The Sierra Nevada Northern Route from Verdi, Nevada to Sacramento followed the old Dog Valley / Henness Pass route from Verdi to Truckee, then westbound on Donner Pass Road (old US 40) up to the top of Donner Pass, then continuing west on Donner Pass Rd, Hampshire Rocks Rd and various other mountain roads parallelling I-80 through Emigrant Gap, Magra, Colfax, Weimar, Applegate, and Auburn. The route then continued southwest on what became old US 40 through the northeastern Sacramento outreaches of Newcastle, Loomis, Rocklin, and Roseville, then turned south on Auburn Blvd to Citrus Heights, then turned southwest, following Auburn Blvd, Del Paso Blvd, and 12th Street into downtown Sacramento to the California State Capitol.
