Answer:
Transcontinental Railroads construction.
Step-by-step explanation:
The Transcontinental Railroads construction in the United States linked the Eastern Part to the Western part and eventually the whole region as a whole.
The first completion of the Transcontinental Railroad's construction occurred in 1869.
