At the time it was planned to be built, no streets existed in this neighborhood but later it appears to be bound by 19th St to 23rd St and Capp St to Harrison St. The half mile track was renovated in 1862, moved slightly to softer ground and renamed 'Willows Trotting Park' but the increasing value of the land for housing proved too much. The final horse race was run at Union Race Course on July 18, 1863.
