behold the lowly bar joist

https://en.wikipedia.org/wiki/Manhattan_Bridge

The Manhattan Bridge was built from 1901-1912 using a device

 known as the Warren Truss.

That “W” design dawned on British engineer James Warren

way back in 1848.

If he alternated triangular supports, the resulting truss was very light, and remarkably strong.

It worked well in big planes, too.

Today it’s called a “bar joist” and it is still used

in all kinds of buildings.

So of course they tried a bridge.

Worked great.

In fact our Manhattan Bridge is the first ever to be based

 on the Warren Truss.

a view from the bridge

One of the big perks for living in the Clocktower
is our wonderful view of the Third Avenue Bridge.

All that is about to change.

The demo is done, the lot is being emptied and hirise buildings
are right around the corner.

No use railing on about it.

Have a good weekend.

under the bridge

I don’t ever wanna feel

Like I did that day.

But take me to the place I love.

Take me all the way.

Yeah yeah yeah.

The old Willlis Avenue Bridge opened on August 22, 1901,

 at a cost of $2,444,511.00

The bridge was replaced in 2010.

Using an inflation calculator, we can see the same buying power in 2010

 is roughly 60 million.

So did the new bridge cost about $60 million?

um.

The Federal Department of Transportation replaced the bridge and the ramp onto Bruckner Boulevard at a cost of $612 million.
