Formula One is closing in on a deal to bring a street race to downtown Miami, which could stage a grand prix as early as October 2019.
The City of Miami Commission is due to vote on F1's proposal on May 10 and its approval will see preparations get underway for a grand prix next season.
F1's American owners, Liberty Media, have been keen to secure an extra race on home soil since taking control of the sport last year, and so far the Miami bid is the most advanced.
"Earlier today the City of Miami Commission took an important step by adding an item to their upcoming agenda, that if approved, will make way to bring Formula One to downtown Miami next season," F1's managing director of commercial operations Sean Bratches said.
