The US Department of Transportation (DOT) has approved US$2.5 billion in private activity bonds for the Brightline West High-Speed Intercity Passenger Rail project in the USA.

The Brightline West High-Speed Intercity Passenger Rail initiative aims to connect Las Vegas, Nevada, with Southern California. Spanning 218 miles (351 km), this High-Speed Rail (HSR) line will predominantly follow the I-15 median, boasting trains with speeds exceeding 186 mph (300 km/h). This will significantly reduce travel time to just two hours, halving the duration compared to car travel. The fully electric and zero-emission system is part of Brightline West's US$12 billion HSR project. In 2020, the DOT sanctioned a private activity bond allocation of US$1 billion for Brightline West, augmenting the total allocation for the project to US$3.5 billion.
