The Milwaukee Mile in West Allis, Wisconsin has hosted American open-wheel car racing events dating back to 1937.

This tradition was famously referenced in the 1969 movie Winning where Robert Wagner's character delivered the line "Everybody goes to Milwaukee after Indianapolis".

After discussions with track, television, and series leaders, the Milwaukee race was pushed back one week to make the accommodation.

At that time, there was a renewed interest in placing the event on its traditional June date immediately after the Indy 500.

After eight years, and after track renovations, the race is scheduled to return in 2024 as a doubleheader on Labor Day weekend.

In the 1963 Tony Bettenhausen 200, Jim Clark and Team Lotus became the first to win an American Championship race with a rear-engined, monocoque car.

After finishing second in that year's Indianapolis 500, Lotus decided to run the car again at Milwaukee and Trenton.

For most years from 1949 to 2009, Milwaukee traditionally hosted a Championship/Indy car race the weekend immediately following the Indianapolis 500.
