Question

Which transportation system had the greatest impact on the United States in the period before the Civil War?

Answer 1

Answer:

It would actually be B. canals  

Explanation:

Railroads were implemented a lot more after and during the Civil War period with the transcontinental railroad being finished in 1869. The period before the war was impacted more by steamboats and canals.

Answer 2

Railroads were far more effective at transporting goods across the country without the risk or delay that comes with sailing. Canals while effective weren't as speedy or reliable as a train since boats are rather fickle things. The turnpikes were being used by wagons and carriages that I doubt could compete with Trains!
