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]
Burnside Bridge: Finished in 1926, the Burnside Bridge, another drawbridge, marks the absolute
center of Portland, because Burnside Street divides the city into its north-south
sectors and the Willamette River divides it into its east-west sectors.
The bridge was one of several built in the 1920's by Multnomah County
(also the Sellwood and Ross Island Bridges) that was linked to a scandal after which
Gustav Lindenthal, a prestigious bridge designer, was brought in to sure
things up. [1] The bridge replaced an earlier bridge built in 1894;
the bridge is 2,308 feet long and is a double-leaf bascule drawspan type. [2]
