Formula 1 says it has an agreement in principle with the owners of the Miami Dolphins NFL stadium to hold a race in the Florida city from 2021.
It is the latest development in an attempt by F1’s owners, US firm Liberty Media, to establish a race in Miami.
The proposal features a new track layout looping around the Dolphins’ Hard Rock Stadium in central Miami.
Organisers face a series of hurdles before the race takes place, including approval by Miami-Dade County.
There has been considerable local opposition to holding a grand prix in the city.
