Industrial Technology
With many people moving to America and many people moving from rural areas to urban areas, the cities in the United States became crowded and new forms of mass transportation were needed. This led to people beginning to build up rather than out, and building forms of transportation that could carry many people at once and carry them quickly. Once the mass production of steel was created, skyscrapers and bridges began to become very popular in cities. Skyscrapers enabled people to use building space much more efficiently. Bridges made it much easier for people to travel. Transportation also became a huge factor in this new era. Things such as horsecars, cable cars, electric trolley cars, subways, and elevated railroads. All of this helped people to travel more efficiently through the cities.
