Authorities are investigating several crashes on Madison's beltline over night Wednesday.
A Fitchburg man was killed after an early Thursday morning crash near Todd Drive. Authorities say 22-year-old Hector Ayala died after crashing his car into a guardrail. A 29–year old passenger in the car was treated for minor injuries. Alcohol is believed to be a factor in the crash.
A four–car, rollover crash near Gammon Road also backed up traffic for hours late Wednesday night. No one was killed, but some minor injuries are reported.
