The first $1 billion of a $5 billion investment into the U.S. air traffic control system has been made, according to the U.S. Department of Transportation's Federal Aviation Administration.

According to an April 27 FAA news release, this first round of funding will be used for nine purposes, including reinforcement of navigation and weather tracking equipment, power systems replacement, enroute flight centers updates, long-range radar renovation and air traffic control towers replacement. 

"Air traffic control facilities are the nerve centers of our airspace system, and a big part of the reason why flying is the safest mode of transportation," U.S. Secretary Pete Buttigieg said in the release. "The Bipartisan Infrastructure Law will repair, replace and modernize the infrastructure that our air traffic control system relies on to keep the traveling public safe for generations to come." 

The $5 billion investment is part of President Joe Biden's Bipartisan Infrastructure Law, meant to "sustain, repair or replace" hundreds of elements in the U.S. air traffic control system, according to the release. The law's total investment into the nation's infrastructure system is $1.2 trillion.

According to the FAA, the projects will create new jobs for local construction workers and supplies, as well as communities nationwide.
