Bit Of A Challenge ?!?
« 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.

See http://www.dailymail.co.uk/video/news/video-1179337/What-like-drive-Japans-famous-Eshima-Ohashi-bridge.html for a video of the drive over the bridge, to get an impression of the true gradient.

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
For the modern man who lives in the city, riding a bike might be one of the only ways to escape the humdrum monotony. To take off and ride. To be both at one with nature and one with the bike. To feel masculine. Adam Piggott
