The Detroit–Windsor Tunnel is an underwater highway tunnel connecting Interstate 75 in Detroit, Michigan, to Highway 401 in Windsor, Ontario, in Canada. It is the second busiest border crossing between the United States and Canada after the nearby Ambassador Bridge.
The tunnel is 2 lanes wide – one in each direction – and almost a mile long. Immigration and customs plazas are above ground on both sides of the border.
We have complete information on this border crossing on our Detroit Windsor Tunnel border crossing page.
Detroit Windsor Tunnel Toll Information
Vehicles pay a fee to pass the tunnel, except for motorcycles, which are prohibited. You can pay the toll with a credit card, debit card, the DWT’s proprietary NEXPRESS Card, or their smartphone app. The tunnel no longer accepts cash!
NEXPRESS is a radio-frequency identification card which provides a discount to the normal toll. This card is different from the transponders used on many North American tollways, so it cannot be used on tollways such as the New York State Thruway. The card is “read” without having to be inserted or swiped in a device. You hold the card near an electronic reader, and the toll gate is raised once the card has been read. Nexpress is the best option if you are a frequent user of the tunnel.
A smartphone app was introduced in 2014 that also provides for discounted tolls. The Detroit-Windsor tunnel app is available at both the Apple and Google online app stores. Travelers can use any toll lane at the tunnel with the app.

Not all toll booths are staffed with toll-takers, so you have to be careful to choose the proper lane. Some automated booths take only coins, credit cards or Nexpress cards, but not dollar bills. There are also NEXUS lanes, which provide a quicker border crossing.
