IMS Suspension Bridge

This image appeared in the Indianapolis Star on Sunday, August 8 1909 as part of the paper's coverage of preparations for the Indianapolis Motor Speedway's first motorized race meets - one for motorcycles, the other automobiles. The motorcycles were scheduled to start August 13 and the cars August 19.
 
This bridge was used for pedestrians to cross the track from the outside to the infield. It was located at the head of the front stretch exiting the northwest turn (turn four) in the approximate location of the tunnel under the track near gate 6 today. You can get a sense of the vista elsewhere on First Super Speedway.
