Location: Portland, Oregon
Steel Bridge: This is the bridge the Amtrak trains cross when leaving Portland to
the south or east. Portland's MAX light rail train crosses on the top
deck, also. Cars use it, too!
Finished in 1912, the Steel Bridge is considered
unique because it is one of the only known dual-lift bridges in the world.
That is, the lower deck (Amtrak and freight trains) can be lifted independently
of the upper deck (MAX, automobiles) to allow some clearance.
The current Steel bridge replaced an earlier on at approximately the
same spot that was built in 1888. [1]
