> Also what the heck am I looking at, this bridge confuses me.

There aren't a lot of photos, but what I'm seeing is sort of a single web "solid truss". Yes, "solid" and "truss" are mutually exclusive, but maybe it will help the thought process.

There are two functions.

First is the fins and the center beam make a rigid, load bearing span across space. So those fins are above the beam, so they are under compression - which is a good use for concrete. They are doing pretty much the same thing that a pony or through truss's webs are doing, except these are solid.

The second function is the side-to-side cantilevers that support the deck and transfer the load onto the center beam. This is show by the under-the-deck photos.

Does this help? Or am I answering the wrong question?

I was just watching some fun Mark Rober videos on YouTube and one of them is on the science of successful egg drop competition. And he was dropping his eggs from an 1898 Parker truss, pin connected, railroad now trail bridge!!

I tracked it down to this bridge. There are some nice shots of the bridge in the video. Here's the link if anyone else cares.

Nice photo, Scott! I cleaned it up, filtered out the color, and adjusted the brightness - and put the cleaned copy up with the other photos.

Posted February 16, 2020

There is a very faded sign saying "private drive". I noticed it when taking photos on the way out. I don't think it is to be believed, as this is an access to what seems to be a public park. The park was closed, but maybe only temporarily.

It appears the bridge has been repaired, and not to badly! Nice to see that it wasn't just torn down and replaced.

Posted February 16, 2020

Well, it looks like the last of the old bridge is about to be removed. Westbound I-44 has used the pier from the old US-66 deck truss, but currently a new westbound bridge is being built. It appears it is done, with eastbound temporarily using the new bridge while the existing eastbound bridge is resurfaced.

I expect that in a month or two the old bridge will be removed - and in the process the piers.

I'm adding a couple photos here in the comments showing the piers. But since it isn't really this bridge I don't really think the photos belong up above.

The first photo shows all the river piers. Taken from the west bank facing east, so the north (upstream) side of the bridge complex. The narrow piers are the ones I'm fairly certain are "leftover" from the US-66 bridge.

The second photos shows the narrow, oldest piers on the left. The next one to the right is still pretty old, presumably from when US-66 was made 4-lane or maybe the first I-44. Next to the right is the newest pier. I think this is replacing the two oldest ones. Furthest to the right is the current eastbound bridge pier

I drove north on MO-47 about a week ago, hoping to drive over the truss bridge one last time. I was too late. I had to drive on the new bridge and most of the deck was gone from the old one - and they were cutting lateral braces to make room for the excavator with the air-hammer head...

But it's not quite gone yet, it seems - though it was scheduled to be demolished today.

From https://www.modot.org/route-47-missouri-river-bridge

The demolition of the old Route 47 Missouri River Bridge, which was tentatively scheduled for April 4, is being postponed due to rising river levels. A rescheduled implosion date is tentatively set for the following week, but a specific date and time will not be released until we get closer to that date.

A parking lot that was a bridge - but it's gone too
Posted January 5, 2019

A few years ago I drove through Rolla, MO and ended up on a side street and spotted an elevated parking lot that the structure was re-used truss bridge pieces. Posts, floor beams, deck, etc. I got a few pictures. Recently I drove through again hoping to see more - but it's gone.

Streetview still has it, though.

https://goo.gl/maps/SRgLoHqzBo92

So far nothing has replaced the parking lot. It was just torn down.

Nice work Melissa!

Nathan, from the lighting, it looks like the sun is behind the photographer. If the camera clock is accurate, the photos were taken late afternoon - and so she probably approached from the south.

Incidentally, google-earth image 2016-10-22 shows a stunning shadow of the bridge on the water.

Hauser Bridge (California)
Posted October 2, 2018

Daniel, You got it right - use "related" to link the new and old bridge. And as I found out, it is only necessary to do it from one side. That is, from the new bridge page, set a link to the old bridge and there will now be a matching link on the old page.

The first one I linked I had to removed a duplicate 'cause I did it from both sides manually.

I vote this bridge as "noteworthy" - if only because it shows that a modern replacement can have some style.

Posted September 25, 2018

Tony, I suspect you have more information to go on than I do - but just looking at the photos I can't see that those two are the same span.

The "sidewalk" on the left in the tall photo sure looks like it is a completely separate span.

And although the view angle is compressing the distance, the rest of the image indicates it was not taken with a long focal-length lens. With that in mind both spans in the tall photo do not look like they could be as long as the span in the wide photo.

On the hill in the background are very straight lines - trolley tracks? Or just wagon tracks? With that, and the tracks on the near side of the bridge, it does not appear the bridge webs could be noticeably taller than a person. Yet the people standing on the bridge in the wide photos indicate the webs on that span are taller than the people.

Neither photo is very good quality, but even so the "lay of the land" doesn't seem to match. The position and size of the trees, the width of the abutment, the height of the roadbed above the fields to the side all suggest it's not the same place.

Then the bridge itself. The left side web in the tall photo does not look like a bowstring truss. Maybe it's just splotches on the poor quality photo - but just doesn't match up.

So - I'm not going to shout "You're wrong" because you may have lots of other data that can prove they really are the same bridge. I'm just looking at the images and what I see sure doesn't look like it can be the same bridge.

That's my opinion - which may be worth no more than the paper it written on. Erm - it's not even on paper. Uh oh.

Posted September 13, 2018

Oh - and the arch seen in the second photo _really_ does not look like it is the same bridge as the first photo.

Posted September 13, 2018

There just isn't enough resolution... The original doesn't have great detail - but judging from the half-tone screening I found in the image it's all we've got. Unless someone can find the photo the newspaper used!

There are a lot of what appear to be lateral floor beams. More often than just at the verticals - which is odd. Having them rest on the lower chord would be a bad idea. Maybe they are just there to tie the deck together?

Regarding the top chord. I think it is round - or nearly round. The shadow line is so consistent at about half-way up that it can't be a flat sided beam. Maybe it's sort of a Phoenix type built up something.

I can see diagonals between verticals in a truss pattern. The top of some of the verticals look "forked", like maybe they are attached to both sides of the top chord.

I sure wish I could see more details!

Ah! Thanks Luke. I see it there on the page where I am working with my photos. So I guess my memory isn't gone, just a bit faulty.

Three truss spans on the ground
Posted September 10, 2018

Here is a Street View link to three Pratt spans sitting on the ground just west of Helena MT.

https://goo.gl/maps/5y5M2MsGmCn

Pin connected, v-laced, and looking like they are in rather good condition.

I did not see a sign suggesting this was a place that was refurbishing them. And it doesn't look like they are being scrapped - which is nice.

But it does seem to be an odd spot for them to be sitting...

Posted September 9, 2018

I saw a number of timber suspension pedestrian bridges. This seems to be a typical example.
