Andretti Autosport issued the following statements on Twitter @FollowAndretti around 11 am ET:
The transporter carrying Colton Herta’s number 88 car to the Firestone Grand Prix caught fire early this morning just about 15 minutes from the track. An update just a few minutes ago reported that the car was not damaged, but there is extensive damage to the pit equipment.
