Which road extended over a thousand miles from Maryland to Illinois and was funded by state and federal money?

The National (Cumberland) Road is the correct answer because it was the first major highway in the United States built by the federal government. Authorized in 1806, it was designed to facilitate westward expansion and connect the eastern states to the western territories, stretching over a thousand miles from Cumberland, Maryland, to Vandalia, Illinois. The project was funded through a combination of federal and state money, exemplifying early American efforts to improve infrastructure and promote economic growth. This road played a crucial role in the movement of people and goods during the early 19th century and is symbolic of the United States' commitment to transportation development during a period of rapid expansion and settlement.

In contrast, the Lancaster Turnpike was one of the first paved roads but did not achieve the same scale or federal involvement. Interstate 70 and Route 66 are modern highways that arose much later and do not pertain to this historical context.
