Blue Water Bridge

A major international crossing, the Blue Water Bridge spans the St. Clair River at the southern end of Lake Huron. Located near the I-94 and I-69 interchange in Port Huron, Michigan, and contacting to Highway 402 in Point Edward, Ontario, the bridge is one of the fastest links between the Midwest and Ontario, as well as the Northeast United States.

Opened to traffic in October 1938, the original Blue Water Bridge formed a critical gateway linking the United States and Canada. In 1997, the second Blue Water Bridge span was opened to traffic. The original bridge now carries three lanes of westbound traffic and the second span carries three lanes of eastbound traffic.

Crossing information

The eastbound Blue Water Bridge tolling operation is cashless. The bridge accepts single crossing payments at toll booths with a credit/debit card or Apple/Google Pay. They also accept pre-paid commercial or commuter accounts available through the EDGE pass program, using RFID tags.

Duty free shopping is located prior to the bridge entrance/toll booths accessed off Pine Grove Avenue (M-25), not the Blue Water Bridge. You can use duty free shopping on your trip to Canada. Once you enter the duty free area, you must pay the toll and cross the bridge into Canada. There are no exceptions.

Blue Water Bridge International Smart Freight Corridor Project

The Blue Water Bridge International Smart Freight Corridor Project will implement a proof of concept of a smart corridor for truck-borne goods movement at the Blue Water Bridge in Port Huron, Michigan, and the Port Huron Port of Entry. The main goal of the smart corridor is to apply data-centered technologies to enable the unimpeded flow of information among commercial carriers, shipping companies, vehicles, border agencies, and  infrastructure operators along a key international freight corridor.
