Important Tunnel Traffic and Detroit Grand Prix Information
The 2023 Chevrolet Detroit Grand Prix presented by Lear is only weeks away, but the work to turn the streets of Detroit into a race-ready track is well underway.
Tunnel officials want to remind Detroit-Windsor Tunnel (DWT) customers that the tunnel will remain open to motorists throughout the racetrack preparations and the Grand Prix race, which concludes Sunday, June 4, 2023. Traffic will be re-routed to allow motorists to enter and exit the tunnel safely without affecting the race route.
Motorists are encouraged to plan ahead and allow extra time for travel due to the increased traffic in the area, especially on the American side of the tunnel, where streets will remain open but with reduced lanes.
In order to access the tunnel between May 31 and June 4, motorists should display a dashboard placard provided by the tunnel’s operators. Placards are available at the Windsor and Detroit toll plazas, or you can download and print the placard from the tunnel website.
For Tunnel Bus Users
From May 30 to June 4, Transit Windsor will only operate a short route between the Windsor International Transit Terminal in downtown Windsor and the Detroit Tunnel Plaza.
