Title: Bridge with the most functioning movable spans
Post by: MCRoads on June 09, 2021, 07:36:35 PM
The rail bridge crossing the US/CA border has 3, 2 lift spans, and a swing span. Any bridges with more than that?

Which one?

I think it is Sault Ste. Marie.

Ah crap, I meant to add that it runs parallel to the I-75 bridge, but forgot to.

Actually, from south to north, the Sault Ste Marie rail bridge has a lift, a bascule and a swing span.  I believe the only instance of a road or railroad crossing a waterway with 3 different kinds of movable spans.

I was wondering that.  Then I figured CA must mean California, and somehow I assumed that meant a BC/CA crossing.  And then I was curious to know how many rail crossings go from California to British Columbia–without it dawning on me that there are two whole states between them.

I hate the possible confusion of CA being either California or Canada.

It's even worse when discussing Ontario, CA.  Ontario can be either a city in California or a province of Canada.
