Answer:
During the Industrial Revolution period in the United States, the aspect that helped people who were migrating west the most was the development of railroads and canals.
Step-by-step explanation:
The development of railroads and canals helped people who migrated out beyond the great frontier to ship products back to the East Coast so they would have a bigger market for their businesses.

However, the United States purchased its steam engines and tracks from England, the United States did not have the industrial capacity yet to manufacture this sort of heavy machinery.
