Know Your Quadrant: Parking Dictates Exit Route

On its website, Indianapolis Motor Speedway shares details of that exit plan, explaining that the area surrounding the speedway has been divided into quadrants, and fans will be expected to leave the area based on where they are parked and not where they are traveling to next.

The Speedway and surrounding area is divided into four quadrants. As you leave the Speedway, you will be directed to the nearest interstate access based on the quadrant in which you are parked – not your intended destination. Find your parking spot on the available map and note where you will be directed.

Google Maps & Waze Will Reflect Real-Time Closures

Indiana Motor Speedway says they have been working alongside Google Maps and Waze, an app popular with travelers, to ensure real-time road closures and directions are updated. Event attendees are encouraged to utilize these resources to help navigate their departure.

Why Pedestrian Traffic Will Delay Vehicle Exits

They also say that they will not allow vehicular traffic to begin exiting the parking lots until pedestrian traffic slows enough to allow for clear roadways. Once the race is over, they say it could take up to an hour for pedestrian traffic to clear.
