Roseville is the largest city in Placer County, California, located within the Sacramento metropolitan area. As of 2019, the US Census Bureau estimated the city’s population to be 141,500. Interstate 80 runs through Roseville and State Route 65 runs through part of the northern edge of the city.
The settlement was originally a stage coach station called Griders. According to the Roseville Historical Society, in 1864 the Central Pacific Railroad tracks were constructed northeastward from Sacramento. The point where the tracks met the California Central Railroad line was named „Junction“. Junction eventually became known as Roseville. In 1909, three years after the Southern Pacific Railroad moved its facilities from Rocklin to Roseville, the town became an incorporated city. What followed was a period of expansion, with the community building more than 100 structures, including what was the largest ice manufacturing plant in the world.
The city was a railroad town for decades, with the railroad employing up to 1,225 people by 1929, out of a population of only 6,425 people. During the 1950s the railroad continued to expand and upgrade, converting its steam engine fleet to all diesel engines by the end of the decade. However, the railroads began falling in the shadow of air travel and the development of the national Interstate Highway System. Another important change during this period was the Washington Boulevard railroad underpass construction in 1950. While this improved the ability of people to travel from one side of the tracks to the other, it meant that people were no longer traveling through the Roseville business district north of the tracks. The completion of Interstate 80 in 1956 shifted the population from downtown to what would become known as East Roseville. The old downtown area slid into a gradual decline.
Roseville has a hot-summer Mediterranean climate that is characterized by cool, wet, usually snowless winters and hot, dry summers. The wet season is generally October through April.
