Some of them wont sink because they float...

There are three floating bridges on Lake Washington in the Seattle area as well. The Lacey V. Murrow Memorial Bridge[0], the Homer M. Hadley Memorial Bridge,[1] and the world's longest floating bridge the Evergreen Point Floating Bridge.[2]

And one on the bottom, no longer floating.

(note -- was a bridge engineer in Seattle and did work on the old 520 bridge when we designed the retrofitted post-tensioning it in the late 90's. Among other tasks, I supervised a guy drilling holes in the bottom of the bridge with a concrete corer. )

"The last tolls were collected on 31 December 2005.”

Let that sink in. They paid for the project and then stopped taking everybody’s money.

That was the plan in Chicago, too...

IMO it's probably a better idea to just keep on collecting them, and putting it away for the future. E.g. the I-5 bridge(s) across the Columbia River had tolls which stopped when Oregon & Washington bought the bridge, and now look where we are at. We have a 110 year old bridge needing replacement and no funds set aside for it. So what they will undoubtedly do is add tolls after spending a few billion to build a new bridge, and eventually it will get paid off. We could have been saving up for the cost and getting interest on it instead of the other way around. Even with a fairly modest toll, when you have a century to save.

This does require some legislative fortitude, however, to set aside the money for real and not just spend it on other things.

We did that here in Seattle, where we have the longest floating bridge in the world, SR 520 across Lake Washington: tolls stopped in 1979 after construction was paid off.

Alas, tolling resumed in 2011, to pay for the complete reconstruction of the bridge. This time we are probably stuck with it, since WSDOT has grown inordinately fond of tolling as a traffic-management tool.

Man in Year 10: See, this is how you do it. No tolls.

Man in Year 50: We need funding for much needed maintenance that has been neglected through sheer incompetence

> Tolls were reinstated on the bridge in 2019 to finance other road projects in the area

:-\

[duped]

Still is the plan, they just keep building and rebuilding the roads.

[BobaFloutist]

How do they pay for maintenance?

[tamimio]

> Plans for a bridge had existed since the 1960s, and after the decision to construct the bridge was passed by the Parliament of Norway in 1989, construction started in 1991. The bridge opened on 22 September 1994

Pretty impressive timeline for an innovative idea.

And here in NY we've had 4 generations working on the 2nd ave subway line and only 3 of planned 15 stations have been opened so far.

I live in Seattle. _Our_ bridges sink!

I'm not an expert but I have seen Titanic (1997) and I would think a floating bridge is most vulnerable to sinking.

[RajT88]

Nah. You see the floating bridge is compartmentalized, so that it is impossible for an entire segment to flood at once and sink.

They are virtually unsinkable!
