The correct answer is D) It is where the last spike was driven to complete the Transcontinental Railroad.
What is significant about Promontory Summit, Utah is that "It is where the last spike was driven to complete the Transcontinental Railroad."
Railroads changed the life of people in the United States. Railroads enhanced the way people traded throughout different regions. Railroads facilitated the transportation of people and goods.
However, the Transcontinental road was a major feat.
The completion of the Transcontinental Railroad was in 1869.
The Pacific Railroad Act of 1862 authorized two companies to connect the East and the West of the United States through the railroad: the Union Pacific and the Central Pacific. They started works in Omaha, Nebraska, to the west, and in Sacramento, California, to the east. On May 10, 1969, they met at Promontory, Utah, and the deed was done.
