Brightline's parent company is getting an influx of cash to help extend the service north.
A state board has given its approval for All Aboard Florida to issue $1.75-billion dollars in federal tax-exempt bonds.
Members have been assured the higher speed rail service won't have a negative economic impact on the Treasure Coast, where some residents and officials have opposed the service.
Brightline began operating between West Palm Beach and Miami this year and is planning to extend north to Orlando in 2021.
