The Erie Canal and the transcontinental railroad helped industrial growth by making the shipping of goods and resources more efficient. These developments had several positive outcomes including:
1) Shipping goods became cheaper.
2) The amount of time it took to ship goods from city to city decreased.
3) Connecting cities/states that before these were made, had very limited opportunities to do business.
4) Allowing businesses to increase the amount of consumers they could sell their product to.
