Title: Bit Of A Challenge ?!?
Post by: alans1100 on June 09, 2015, 09:29:41 PM
Can’t see the bike lane! Looks like pedestrian lane on the LH, I would imagine stairs.

 
This is the Eshima Ohashi bridge in Japan. It’s the third largest rigid-frame bridge in the world at 44 metres tall. And judging by its looks, it would also probably qualify as the world’s scariest too. The mile-long bridge was built on the banks of Lake Nakaumi, connecting the cities of Matsue and Sakaiminato. If you’re wondering why it looks more like a rollercoaster (or should I say, road-er coaster) than a bridge, it’s because it was designed to be high enough to let ships pass underneath.

It has a gradient of 5.1 percent on the Tottori Prefecture side and 6.1 percent on the Shimane Prefecture side, making its slope look like the apex of a rollercoaster. In addition to wearing a seatbelt, you might want to bring a barf bag when driving along this road.

You would need a full tank of fuel before attempting that climb, just imagine if the fuel pick up was uncovered. :eek :eek

The use of a telephoto lens to take the photos causes what is known as "foreshortening" which is a change to the perspective geometry, and it makes the bridge look much steeper than it actually is.   A 5.1% gradient is actually not very much.

Quite right.  There are a few 16% gradients around here that are a blast to hammer the ST1300 up to the top, accelerating all the way.      :thumbs
