After the Civil War, most Texas farmers were stuck in a life of subsistence farming. Commercial agriculture can survive only when there is an efficient way to bring goods and people together. Farmers need to ship crops at a minimum expense to the people who want to buy them, and they need to have goods and equipment shipped to their farms. What was the solution to this problem

Dredging Texas rivers to make them navigable for shipping

The expansion of railroads in Texas

The construction of the interstate highway system

The development of robotic oxen and aerodynamic carts made of aluminum alloy
