Bridges With Ceilings:

What types of bridges are for example Bridges Over Kanawha River And Ohio River? I want to call them Truss Bridges but I might be Wrong. They are much larger than Truss Bridges, but still much smaller than Cable Stayed Suspension Bridges such as Golden Gate or Chesapeake Bay Bridges.

They have a giant arch of some type in the middle of them, but also have beams that extend outward, in some cases over the entire length of the bridge.

I really like these beautiful and also hypnotic bridges.  :D

What are they and why aren't there more of them?  :)

Also I would like to point out Cheesepeake Bay Bridges were built at different time periods. One is a narrow two lane bridge and the other is a wider two lane bridge but what I consider to be a shoulder is actually an additional lane (a 3 lane bridge). Both of these bridges look different from each other. It seems that the older bridge looks stronger than the newer bridge. It has more beams. You might say that the older bridges are over-engineered but I think that if they have more beams, then they would last longer.

Which is another reason why I want to see more of these Bridges With Ceilings.

Do you mean, like, double-decker bridges like the Gerard Point Bridge in Philadelphia?

I think he's referring to tied-arch bridges with the apex of the arch above the bridge deck -- and invariably some sort of cross-braces connecting the sides of the arch (the "ceiling", so to speak, at least from the viewpoint of someone traversing the deck).  However, without specific reference to particular structures, who can be certain?  The OP needs clarification.

Three of the four Kanawha River bridges along I-64 are truss bridges -- the one at St. Albans, the one leading into downtown and the Chuck Yeager bridge at the beginning of the WV Turnpike.

With the mention of a "giant arch"  and the Ohio River, I assumed something like this.

These would generally be referred to as tied-arch bridges as sparker pointed out. Other types of through arch bridges would present a similar driving experience as far as the motorist is concerned.

As to why there aren't more, maybe a PE could chime in. In general, there are a number of criteria to be considered (cost, length of span, load requirements, serviceable life, terrain, etc.), and that will guide engineers toward some types and away from others. This manual from the FHWA goes into more detail on bridge type selection: https://www.fhwa.dot.gov/bridge/steel/pubs/if12052/volume05.pdf

Yes, and also these. I finally found the name of one of them: The Chuck Yeager Bridge. It is two green bridges with a curved design in the middle and additional beams on the edges which continues even when crossing over land. (somewhat similar to the I-64 bridge.) The bridge in Pennsylvania looks just like a dark blue bridge in West Virginia.

I couldn't find a sufficient Street View of this bridge, but there are plenty of images on Google that clearly show the design of the bridge.

Another pointier bridge. The Ceiling continues even farther onto land more than The Chuck Yeager Bridge.

The other bridge mentioned by kphoger is the U.S. 35 between West Virginia and Ohio. It is the pointiest of bridges, resembling a small cable stayed suspension bridge. But it is still a similar design.

Two other nearby bridge designs is the dark blue bridge but the Ceiling isn't as long. This design is very common.

And another pair of bridges has no Ceiling even though it crosses the Kanawha River. Why not?

The Yeager Bridge is actually two different type bridges. The southbound bridge was part of the original two-lane West Virginia Turnpike. The northbound bridge was added when the turnpike was four-laned. The new bridge's design is not an exact copy of the old bridge. The age difference in the two bridges is noticeable both when driving across the bridges and when passing below them on US 60.

According to Wiki, https://en.wikipedia.org/wiki/Cantilever_bridge That is the best description for most of the bridges I noticed. Also, it seems that these bridges are being replaced by various Suspension Bridges and Cable Stayed Bridges, and that U.S.A. is no longer building Cantilever Bridges. Other places still construct Cantilever bridges. But Abraham Lincoln Bridge is next to the John F. Kennedy Bridge is why I think that U.S.A. is phasing out the Cantilever Bridges. I think that is unfortunate some of these Cantilever Bridges are being replaced with what appears to be bridges that aren't as strong. The Tacoma Narrows Bridge Collapse For Example. I don't think Cable Stayed Bridges have the same risk but I still love Cantilever Bridges.

So...you think the current bridges, which have lasted nearly 57 years (1950 bridge) or 10 years (2007 bridge) respectively are weaker than the bridge that fell down after only four months? :D

New Tacoma Narrows Bridges lasted that long because there was no wind.

There was and is plenty of wind through the Narrows.  The 2nd iteration of the bridge, as well as its parallel span, featured design plans that were modified to account for the probability of winds of that nature occurring regularly.  In other words, the bridge engineers learned from their mistakes and applied it appropriately.

Correct. Just like in the Simpsons movie, a gigantic globe was put over the town the bridge is located in, not only sealing off the bridge and the town from everything else, it also kept the wind away.

Okay so this proves that the reason why people want Cantilever Bridges to be replaced is because you think they are ugly and whether or not it is ugly determines which type of bridge is built?

What?  No.

The truss bridges are more expensive to build and maintain.  That is all there is to it.
