The photo shows the original road course. The track was paved in 1954 and the road course added then. The loop in the bottom right of the photo was never used, for reasons I just do not know. The first road race at the track was in 1954 and the road course was either not ready or unsatisfactory. Hence the mile oval only was used, but with haybales placed here and there to form an occasional chicane. Before the next road race, in 1955, the loop was removed.
The road course was repaved about eight-ten years ago, and has been used by the SCCA Milwaukee region for events up until this year. However, this season the usual Milwaukee SCCA regional is not being held. Simply put, the Region's finances and the race's income were not enough to justify the track's rental fee. So the road course is dormant, at least for the time being.
The half mile oval did not have a long life. But the quarter mile oval was in regular use for years, as every Thursday night during the summer the track stage races for modified stock cars. The quarter mile was still in existence in the early 1960s, but sometime in that era it was removed.
Yes, the Green Bay Packers did play here. For many years they played up to three regular season games in Milwaukee, and up until the 1950s those were played on a gridiron layed out in the infield of the race track. In fact, (now here is trivia!) the 1939 NFL Championship game was played at the Milwaukee track.
