The US American infrastructure is reported to be improved in 2025, thanks to federal investment through federal grants under the IIJA Act of 2021 and other initiatives to strengthen infrastructure development. The article covers the major US federal infrastructure grants that have helped improve the infrastructure.
US Federal Infrastructure Grants 2025
The federal government introduced the Infrastructure Investment and Jobs Act, or Bipartisan Infrastructure Law, in 2021, and authorized the funding of $1.2 trillion for infrastructure and transportation. The act addresses the need for energy power infrastructure, water infrastructure, etc.
The federal government has introduced many federal grants under the legislation that have provided the needed support to a variety of infrastructures. Under the $1.2 trillion funds, around $500 billion was allocated for investment in broadband, bridges, water, rail, airports, power grids, and other infrastructures.
A good amount of funding was distributed through formula and competitive grants, where formula grants are a portion of funds distributed to state and local authorities as per federal formula, whereas the competitive grants are programs that have been offered to eligible applicants.
