Final answer:
Mr. Jackson's bet did not directly contribute to the development of roadways. The development of roadways was a result of the construction of national highways and other road projects funded by federal and state governments.
Step-by-step explanation:
Mr. Jackson's bet did not directly pave the way for the development of roadways. The Cumberland Road, a national highway funded by the federal government, was one of the key developments that led to the creation of a transportation infrastructure. Other road and canal projects were also supported by federal and state governments, which aimed to facilitate commerce and settlement in the West. Additionally, the Federal Highway Act of 1956 played a significant role in the construction of the interstate highway system.
