The federal government has a long history of investing in infrastructure, dating at least as far back as 1806 when Congress authorized the construction of the National Road, the first highway built entirely with federal money.
In the centuries since, federal, state, and local governments have spent trillions of dollars on the networks and facilities necessary to help the country function. There is no agreed-upon definition of infrastructure, but broadly it refers to facilities, structures, and utilities intended for long-term use.
