Gordie Howe Bridge Opens June 15, What Cross-Border Fleets Need to Know

When does the Gordie Howe Bridge open to truck traffic?

The Gordie Howe International Bridge over the Detroit River opens to commercial traffic June 15, following a June 12 ribbon-cutting ceremony. The span has been under construction since 2018 and was financed entirely by Canada at a cost of $4.6 billion. The Windsor-Detroit Bridge Authority will operate the crossing, which links Michigan to Ontario and provides a second commercial route alongside the privately owned Ambassador Bridge.

The new bridge was built to reduce shipping congestion in a region that moves heavy automotive freight. Cross-border carriers serving Detroit-area OEMs and Tier 1 suppliers have relied on the Ambassador Bridge as the primary commercial crossing for decades. The Gordie Howe span offers an alternative, though toll rates have not been publicly disclosed and revenue-sharing terms between Canada and Michigan remain tied to Canada recouping its construction costs first.

What the toll structure means for fleet costs

Canada and Michigan agreed to share ownership of the bridge, with toll revenue split once Canada collects enough to cover the $4.6 billion build cost. No timeline has been published for when that break-even point will occur, and no toll schedule has been released. The Ambassador Bridge currently charges commercial vehicles based on axle count and weight, with rates adjusted periodically. Fleets running regular Detroit-Windsor lanes will need to compare published Gordie Howe tolls against Ambassador rates to determine per-trip cost impact once the authority releases pricing.

Border traffic volume has declined in recent months, partly due to Canadian travelers avoiding U.S. crossings. Lower-than-expected traffic could extend the payback period for Canada's investment, which in turn delays Michigan's share of toll revenue. U.S. Ambassador to Canada Pete Hoekstra told Detroit media in April that higher costs and reduced border volume raised questions about whether Michigan would see proceeds as originally projected.

Political uncertainty around the opening

President Donald Trump posted in February that he would not allow the bridge to open until the U.S. was "fully compensated for everything we have given" Canada and until Canada "treats the United States with the fairness and respect that we deserve." No public statement has clarified whether those conditions have been met. The White House did not respond to requests for comment on whether it supports the June 15 opening.

Trump's February statement followed a meeting between U.S. Commerce Secretary Howard Lutnick and the owners of the Ambassador Bridge. Canadian Prime Minister Mark Carney said June 9 that the bridge will be "open at the end of the week," though he did not specify whether that referred to the ceremonial event or the traffic opening. Michigan Governor Gretchen Whitmer reportedly held direct talks with the White House on the ribbon-cutting event, according to the Detroit News.

What this means for cross-border carriers

The Gordie Howe Bridge adds capacity for fleets moving automotive parts, finished vehicles, and general freight between Michigan and Ontario. The span includes a U.S. port of entry on the Michigan side, which will handle customs and inspection for northbound and southbound commercial traffic. Carriers will need to confirm whether their existing FAST (Free and Secure Trade) credentials and C-TPAT (Customs-Trade Partnership Against Terrorism) certifications apply at the new crossing or require separate enrollment.

The bridge's opening does not change equipment requirements for cross-border operations. Trucks must still meet both U.S. and Canadian safety standards, including annual inspections under the National Safety Code in Canada and FMCSA regulations in the U.S. Fleets should verify that their insurance policies cover both crossings, as some carriers have historically maintained separate coverage for the Ambassador Bridge due to its private ownership structure.

Route planning software and GPS systems will need updates to include the Gordie Howe Bridge as a selectable crossing. Carriers running dedicated Detroit-Windsor lanes should monitor toll announcements from the Windsor-Detroit Bridge Authority and compare total trip costs, including any time savings from reduced congestion, against their current Ambassador Bridge expenses. The bridge's long-term viability for commercial traffic depends on toll competitiveness and whether political disputes over U.S. support affect operations after the June 15 opening.
