In 1916, the United States created the Federal-aid Highway Program with the primary objective being the improvement of rural roads. This changed with the Federal-Aid Highway Act of 1944, which authorized the first specific funds for urban highways, specifically the creation of a formula for the distribution of federal-aid funds among the primary, secondary, and urban systems. Today, there are three federal-aid systems: The Interstate Highway System, the Federal-aid Primary highway system (FAP), and the Federal-aid Secondary highway system. The Federal-aid Secondary highway system is broken into secondary non-urban (FAS) and secondary urban (FAU). The interstate system consists of routes connecting and running through and around major urban centers. The FAP consists of a system of connected main highways, while the FAS are composed of principal secondary and feeder routes. Both aid systems are chosen by state highway departments and local officials, but are subject to approval by the Bureau of Public Roads. Having roads designated as federal-aid means that the federal and state governments provide funds and take care of repairs instead of the community in which the road is located. This allows the local government to spend money in other areas.
