Some of the world's longest bridges over water are absolutely massive

I was putting together a list of the world's longest bridges over water, and the scale of some of these crossings is hard to imagine. The Hong Kong–Zhuhai–Macau crossing, for example, spans about 55 km as a complete bridge-and-tunnel system.

The list also includes Lake Pontchartrain Causeway in Louisiana, Jiaozhou Bay Bridge in China, and King Fahd Causeway connecting Saudi Arabia and Bahrain.

I'm curious, which of these crossings would you most want to experience in person? And are there any impressive bridges you think deserve more attention?

Bridge Transitions: Hundreds of years of engendering history and work; why are we unable to design effective bridge transitions?

6 Upvotes

I just spent 2 days traveling interstate 75 north from Florida to Michigan. A large majority of bridge transitions want to absolutely destroy my vehicle suspension and potentially rip my front end apart. Why are we unable to design a smooth and lasting bridge transition?

I just recently drove across this railroad bridge! It was a historic railroad bridge and was converted to a single lane road toll bridge by a farmer in the 1960s. I didn't even realize it was an old rail bridge until a week later. I thought you all might enjoy 360 4K VR driving tour video of me crossing. Enjoy! Get the full 360 view by watching in YouTube!

Is there a proper name for this feature of Victorian railway bridges?

Thumbnail
gallery
111 Upvotes

Outlined in the images attached is a feature that's almost always present in Victorian bridges - most specifically girder type bridges transitioning to a viaduct either side.

It's the top part of what is usually a slightly projecting pier/pilaster built onto the side of the bridge abutment. It's essentially decorative, providing a visual stop-end to the bridge/viaduct junction and usually hiding the end of the girder which sits on a bearing just behind it. They usually look very substantial from the front but this top part, the part that sits above the level of the track is often quite slim front-to-back. Sometimes they have a kind of L-shape in plan, forming a sort of pocket behind that the girder end sits in.

Although they seem to have almost always been part of the original design, actually not many of them survive in their original form, presumably because with the passage of time they become seen as serving no useful purpose and a maintenance headache. So very often they are either removed completely or simplified to blank stubs of brickwork.

But do they have a proper name? What would you call them? Abutment parapets? Abutment pilaster-tops?

I'm looking for a term that describes specifically that top part, not the whole pier from ground level up. The bit I've outlined in red in all the images.
