MDOT Blue Water Bridge tolling system upgrades to begin Aug. 20

PORT HURON, Mich. ­- The Michigan Department of Transportation (MDOT) Blue Water Bridge (BWB) is alerting customers that it plans to upgrade tolling software for eastbound BWB customers on Aug. 20.

Over time, BWB will discontinue the current cards and transition to 6C RFID windshield tags that are automatically read by the bridge tolling system when drivers pull into a lane. Additional information about the availability of tags for all account holders will be forthcoming.

Account holders will continue to use but there will be a new look and new access instructions. A new web portal will allow customers to manage their account more effectively. This will include the ability to review transactions, make one-time payments or set up automatic payments, request new or replacement tags, cancel tags, generate statements, and more.

A few important reminders for existing customers:

  • All current account information and balances will automatically transfer over to the new system. Customers will need to re-enter payment information in the new system if automatic payments are currently set up. Customers can log in using their previous account number; however, they will be prompted to create a new username and password.
  • Current cards will continue to work, although they will eventually be phased out. Customers will receive advance notice when this happens.
  • Before the new system goes online, there will be a “freeze” period on accounts. Creation of new accounts is currently frozen. No deposits to existing accounts can be made after 10 p.m. Aug. 18. Existing customers will want to ensure they have enough funds on their MDOT BWB pre-paid account to cover any crossings made between Aug. 18 and 20. The freeze will be lifted when the new system goes live. All valid cards can continue to be used on their accounts during this period.
  • Account holders with the Federal Bridge Corporation Limited (FBCL) can also expect to receive more information in the coming weeks.

Some helpful online guides will be available after Aug. 20 to explain functions of the new system and give instructions on how to perform tasks such as making payments, requesting new tags, etc. If you have any questions, call 810-984-3131 and select option one, or e-mail
