The four pieces of the Gordie Howe International Bridge

Opening day marked the first traffic

The bridge authority records passenger and commercial crossings on 27 July 2026. The six-lane bridge uses an 853-metre main span within an overall crossing length of about 2.5 kilometres. Source 2 Source 3

The ports of entry are large facilities in their own right

The original project descriptions put the Canadian site at about 53 hectares and the US site at about 68. Both include vehicle inspection and supporting functions. The Canadian facility also contains the toll collection and maintenance areas described by the authority. Source 1

Inspection lanes can be assigned to different traffic

The Canadian border agency identifies 24 primary inspection lanes and says the layout can support up to 16 commercial or 19 traveller lanes. It separately lists 12 commercial secondary examination docks and two enclosed commercial examination bays. These figures describe site facilities and lane configurations. Source 4

The interstate connection is part of the project

The Michigan interchange includes ramps between the US port of entry and I-75, as well as local road improvements. The agency describes approximately three kilometres of I-75 modifications. The bridge gives the Windsor area a third land port of entry alongside the Ambassador Bridge and Windsor-Detroit Tunnel. Source 1 Source 4
