The Federal Highway Administration (FHWA) is a part of the U.S. Department of Transportation. Its main job is to oversee the nation's highways and ensure they are safe and efficient for all drivers. The FHWA provides funding, guidance, and support to state and local governments to help them build and maintain their road systems. In addition to managing highway construction, the FHWA also focuses on improving road safety and reducing traffic congestion. They work on various programs that promote better transportation options, such as public transit and bicycle paths, to create a more connected and sustainable transportation network across the country.
