Waverly Bridge

In response to Jason, your arguments don't hold that much water. For one, if these concrete slab bridges really are better and stronger, then why are routes with higher traffic volumes getting brand new Through truss bridges, and cable stayed bridges, such as the new Bridge in Hannibal, the new Liberty 291 bridge, and the Discoverdy bridge in St. Charles? If they MUST build a concrete slab bridge, then my opinion, is that they can "somewhat" have the best of both worlds. Why not build your concrete slab, but instead of concrete barriers for the guardrails, why not line the bridge with 5 foot steel pony trusses. There are no drawbacks, and here are the benefits:

1: Cheaper in the long run, because the steel pony trusses will last for 70-90 years, while those concrete barriers will crumble in 20. And those trusses can be fabricated in factory and shipped to the site.

2: You at least have a "Semblance" of a historical look, important for areas of the country which depend highly on tourism to drive their economy.

3: Pony trusses do not create a complete visual barrier, one of the biggest complaints these concrete bridges draw is that tourists and locals alike cannot SEE the breathtaking view of the river when they drive over it (Unless thyer'e in a semi-truck).

4: Pony trusses would not create any height restriction.

THat isalmost EXACTLY what I would say. Bridges can be attractice AND safe!!! Boring concrete bridges should NEVER be built!!!

I totally agree!! I saw the prints of the NEW 35w.BOOOORING!(YAWN). I think bridges can be attractive AND safe!! ugly concrete eyesores don't appeal to us bridge freaks!!

Too address the pedestrian crossing, this is an option but the code for pedestrian crossing is based off square footage and it adds up pretty fast. So if a bridge is structurally unsound then it is hard to turn it into a pedestrian bridge and meet code.

An option to save a bridge is to form a not for profit organizantion and take ownership of the old structure, while providing area for the new one (if the new one was to go over the old). Then it is the not for profit's bridge, they can repaint it or repair it or do as they please with it. Counties and road departments have harder time with this because if thier is a problem and somebody gets hurt they can be liable in court for not meeting code.

First to address how safe you feel. Concrete I girder or large steel girder bridges are alot stronger bridges than truss designs. Truss bridges are usually fracture critical, so if ONE member fails ALL fail, like the I 35W bridge structure. Now it is being recommended all of these old truss bridges should be evaluated to ensure the gusset plates are strong enough.

A multi girder bridge over 3 girders, like 4 or 5 or more are not true fracture critical, meaning that they can still stay standing if one or more things fail. The Concrete I girder Bridges are the STRONGEST BRIDGES MADE today. They are also one of the cheapest ways to build bridges.

A barge hitting the bridge has NOTHING to do with what type of super structure it is. The barge will damage the piers or webwalls. These are designed stronger today then in the past. If the substructure fails no matter what the super will fall.

I agree that better looking bridges would be great, I love to look at them too, and would love to design them but they cost too much. Alot of the reason nice concrete arc bridges and truss bridges were made was because labor was cheap, so who cares if they were labor intensive to build. Now you have the opposite the labor is the expensive part so you precast as much as you can and minimize intensive labor (Iron work). This is becuase of prevailing wage rates mandated, if they were not used then the cost would go down.

I passed over this bridge alot while growing up, and think these MO river bridges of similar truss style look very good but looks are not an option sometimes when there is no money to build it.

Yeah! I agree. For major or navigable rivers like the Missouri, I think more interesting bridges need to be built like cable stayed, tied arch, or continous truss. Also, I think these boring stringer and girder bridges may not be safe if hit by barges, so I'd feel more safe crossing an older truss or intersesting type of bridge!

Yuck!!! What a piece of crap that new bridge is!!! I honestly think it's ridiculous that new bridges are being so boringly!!! i think they should have left the old one up for pedestrians and cyclists. As a person who lives in a college dorm that has a nice old-fashioned lounge, I think that old pieces of history should never be destroyed. Why does the need for a funcional and cost-effeicient bridge preclude it being INTERESTING!!??? Why can't bridges be safe AND interesting??

As I understand when this bridge was being built, a bridge worker helping to construct the bridge fell into one of the

piers on the main span during the pouring of the concrete. The ill fated worker would have been sealed in the pier like a tomb. During the demolition of this bridge was the worker found?
