This is the best picture of the near entirety of the International Bridges. It is fascinating how the International Auto Bridge was built:

This bridge is a complex structure. The minor spans are all deck plate girder spans. There is a deck truss span over the Power Canal on the Michigan side. The continuous truss unit over the U.S. canals is a four span through truss with two arch-shaped spans featuring suspended deck, giving it an arch-like shape. This style of continuous truss unit usually only has a single arch-shaped suspended deck span, making this part of the bridge extremely rare.
The span over the Ontario canal is another continuous truss unit with suspended deck, but this unit is of traditional arrangement with only a single arch-shaped suspended deck truss span. The bridge is noted for its sag in between these two through truss units, which was done because under-bridge clearance was not a concern at that part and so to reduce costs, the piers were built with a lower height there.
The International Bridge lacks any v-lacing or lattice, and all connections are bolted. There are rivets on the built-up beams however. The concrete piers are tall and impressive, but feature minimal aesthetics, especially when compared to a bridge like the Blue Water Bridge.
