California's isolation was largely ended by the completion of the transcontinental railroad in 1869, which connected the state to the eastern United States. This infrastructure development facilitated the movement of people, goods, and ideas, significantly boosting California's economy and population. Additionally, advancements in communication technologies, such as the telegraph, further integrated California into national networks, reducing its geographical and economic isolation.
