Select a single event in Table 1-1 and explain why this is a significant achievement in the history of transportation.

What will be an ideal response?


In my opinion, the completion of the first transcontinental railroad in 1869 was the most significant transportation event in U.S. history. This is because the completion of the railroad meant that goods and people could now be transported with relative ease to the western part of the country. This also meant that the development of the west would become more intense. The completion of the railroad spawned the development of the remainder of the U.S., which facilitated trade on both coasts.
