Indianapolis 500 Scaffold Collapse
During the pace lap of the 1960 Indianapolis 500, a privately owned makeshift scaffold holding more than 100 spectators collapsed in the Speedway infield — killing two people and injuring dozens more. Private scaffolding was subsequently banned at the venue.
Incident Overview
The 1960 Indy Scaffold Disaster
On 30 May 1960, during the pace lap of the 44th running of the Indianapolis 500, a privately owned makeshift scaffold collapsed in the infield of the Indianapolis Motor Speedway, Indiana.
The structure — described as an aluminium-and-board tower approximately 30 feet tall — had been built by Wilbur Shortridge Jr., who charged spectators around $5 to $10 each for a vantage point on top. More than 100 people were estimated to be on the scaffold when it gave way.
Sources describe the crowd shifting forward as the cars took their starting positions, causing the structure to tilt and then collapse onto the crowd below. Two people were killed and dozens injured. Following the incident, private scaffolding was permanently banned at the Indianapolis Motor Speedway.
Venue & Location
Indianapolis Motor Speedway
Location: Indianapolis Motor Speedway, Infield, Indianapolis, Marion County, Indiana, United States.
Source wording on the precise infield location varies: the IndyMotorspeedway.com reproduced UPI text places the scaffold in the "infield of the Speedway's northeast turn," while Rare Sports Films and some later secondary sources describe the collapse as occurring in "turn three."
Both descriptions refer to the same general infield area. The reviewed sources do not fully resolve this location wording conflict.
