Settlers in California overcame geographical challenges by using new transportation networks like highways and bridges to connect remote areas to urban centers. They also made use of advanced engineering techniques to build tunnels and roads through mountainous regions, as well as constructing dams and aqueducts to manage water resources. Additionally, they developed agricultural innovations to cultivate arid land and adapt to California's diverse climates.

Building the transcontinental railroad was challenging due to geographic obstacles such as the Sierra Nevada and Rocky Mountains, vast expanses of desert, and harsh weather conditions. These obstacles required extensive and innovative engineering solutions to lay down tracks across rugged terrain and varying landscapes.

The area likely to see the greatest percentage increase in urban population due to the completion of the Transcontinental Railroad is the western United States, particularly areas along the railroad route such as California, Oregon, and Utah. The railroad helped facilitate easier transportation and access to these regions, leading to rapid urban growth and development.

The completion of the transcontinental railroad in 1869 made travel and trade easier, allowing for faster and more accessible transportation to and from Omaha. This likely led to a boost in economic opportunities and development in the area, attracting more people to the region and contributing to population growth by 1890.

The building of the transcontinental railroad faced challenges due to the rugged terrain of the Rocky Mountains and Sierra Nevada as well as the vast expanses of deserts and plains. The construction crews had to navigate through steep grades, harsh weather conditions, and limited access to resources, making the project a formidable undertaking.

A transcontinental arch refers to an arch that spans a continent or connects two continents. It can also be used to describe a large geological arch formation that extends over a large distance.

Iris Chang wrote "The Chinese in America: A Narrative History" to highlight the contributions and struggles of Chinese immigrants in American history, including their involvement in building the transcontinental railroad. Chang explored the challenges faced by Chinese laborers and their impact on shaping American infrastructure.
