A grandstand at the World Wide Technology Raceway in Madison was knocked onto the drag strip during storms Thursday, and the track has canceled drag racing scheduled for this weekend.
“The west grandstands of the World Wide Technology Raceway drag strip suffered extensive and permanent damage due to high winds,” the track said in a news release Friday. “As a result, the drag strip will be inoperable this weekend while facility operations clear the track’s racing surface.”
Races scheduled for late April and early May will take place, the news release said.
