September 14 – Penang Bridge Officially Opened to Traffic

Posted on September 14, 2018

Yeah, I didn't do enough of this (above).
Or any of this!
I didn't do enough fiddling around with materials and construction sets as a kid, and I didn't have a clue, for years, how bridges and arches and tunnels were made. Bridges, especially, used to puzzle me - how could they be built in deep water and especially in moving water. And really looooong bridges were that much more puzzling.

Hikers still use super primitive,
temporary bridges when necessary.
Of course, early humans and other animals have always used and made simple bridges like a log placed so that it crosses a stream. 

More complex bridges have been built since ancient times; Ancient Romans, for example, used mortar and arches to build strong bridges. 

Here is a video that shows three ways in which bridge supports are built in water.

Today is the anniversary of the opening of the Penang Bridge in Malaysia. It is is more than 8 miles long (more than 13 km long), and it connects a peninsula with an island.

When your whole nation is a peninsula and islands, you're
going to have to build a few bridges!

Above and below: two views of the Penang Bridge.

There are longer bridges in the world - longer bridges, even, in Malaysia! The officially longest bridge in the world is the Lake Pontchartrain Causeway in Louisiana. Many photos of this bridge look a bridge that goes from nowhere to nowhere - because you cannot see land at either end! 

But of course, the 24-mile (38-km) long bridge does go from somewhere to somewhere - it connects two sides of a lake.

Here is a video of some unusual and cool bridges. And here are a few pics of other assorted interesting bridges:

Ahhhhhh - I NEVER want to travel on this ultra-high bridge!
Found in France, the Millau Viaduct is the highest bridge in the world.

Oh, man, I went to Wuppertal, Germany, and I
didn't know to look for this cute LEGO bridge!

Cool - a nice LOW bridge. Found in the Netherlands -
and much more my style!
I'm not sure whether the rolling bridge (in London, U.K.)
or the wavy bridge (in Singapore) have any reason to
be this weird, other than the weirdness itself?
