The thundering sound of hoof beats at the shuttered Hazel Park Raceway is gone and has given way to the rumble of trucks and bulldozers as workers demolish all the buildings at the former horse track. Demolition got underway earlier this month and is expected to finish sometime in November, said Hazel Park City Manager Ed Klobucher. The horse barns are already torn down. The former Clubhouse -- where customers ate, drank, gambled and watched the races for 69 years – is the largest building on the site still standing, but demo work there will start in a couple of weeks.
