1932+1989 USA-90 Danziger Bridges over the Industrial Canal in New Orleans, LA

1932: (Bridge Hunter)

1989: (Bridge Hunter; 3D Satellite)

The formal name for the Industrial Canal is the Inner Harbor Navigation Canal (IH-NC).

When the Industrial Canal was built in 1919, the Almonaster Avenue Bridge carried the Old Spanish Trail across the canal. That road was designated US-90 in 1926. In 1932 the new Chef Menteur Highway including the 1932 Dansiger Bridge was opened and US-90 was moved to that route. [Bridge Hunter Description]

I normally don't bother with a portal view, but this lift bridge design is unique and this is the only way to see the counterweight.
