IndyCar driver Justin Wilson crashed Sunday at Pocono Raceway and suffered a traumatic brain injury that left him in a coma. He died the next day.
As a tribute to Wilson, a motorcade of IndyCars and Holmatro Safety vehicles crossed the Golden Gate Bridge on Thursday with the Astor Cup. It will be awarded to the champion when the season ends this weekend in Sonoma.
Wilson's Andretti Autosport teammate, Marco Andretti (grandson of Mario, son of Michael), led the group in Wilson's No. 25 car. Two Holmatro Safety vehicles, the same that were on site at the Pocono crash, flew Justin Wilson flags from the back of their trucks.
Drivers Will Power, Graham Rahal, Josef Newgarden and James Hinchcliffe also participated in the motorcade. Wilson, a native of England, was 37. He was the first IndyCar rider to die in action since Dan Wheldon in 2011. A charity, Wilson's Children's Fund, has been established on behalf of his family.
North-bound traffic on the bridge was closed to accommodate the motorcade:
