The first images of the track layout for the Miami F1 race show that it will run around the city's port, and running through an area used previously by IMSA, Champ Car and Formula E.
Plans for the event, scheduled to start in October 2019, will be considered at a meeting of the city commission next Thursday.
The track passes around the American Airlines Arena, which is the home of the Miami Heat NBA team, and the pit and paddock area will be located adjacent to it.
From the start/finish, it runs down Biscayne Boulevard, before it loops around and returns on the same street. It then heads right towards a high-speed section along Port Boulevard, which crosses a bridge.
After a hairpin, it returns on NE 6th Street on the same bridge to a second hairpin, before a run along the waterfront around the arena, through a series of 90-degree turns, back to the start/finish line.
Some elements of the track resemble the original Miami street race layout, first employed by IMSA in 1983, and which also used Biscayne Boulevard and ran around the area where the arena now stands.
In 1986 local development meant that the IMSA event was later moved slightly north to a new venue at Bicentennial Park. It was also used in reverse direction for a ChampCar race in 1995, won by Jacques Villeneuve.
However, CART returned to the original location for two races held in 2002 and 2003, which had some elements in common with the IMSA track, and once again featured Biscayne Boulevard.
In 2015 racing returned when Formula E ran on a short 1.4-mile course that went around the arena, but then swung north.
The proposed F1 layout is the first to run across the water and back, although a similar idea was once discussed by Bernie Ecclestone and original Miami GP promoter Ralph Sanchez in the eighties.
It's clear that the hope is that the two long straights, both of which are followed by heavy braking areas, will contribute to some Baku-like action.
