Seemingly Simplistic - Highly Technical ~/?x=entry:entry170612-022539 2017-06-12T02:25:39+00:00 2017-06-12T02:25:39+00:00

The Peace Bridge was designed by Spanish architect Santiago Calatrava.  A double helix tubular truss for both pedestrians and cyclists crossing the Bow River in Calgary, Alberta, Canada.

Images-2.jpgThe design required a different approach, due to the strict requirements with no piers in the riverbed or vertical elements above, and with a restricted height - resulting in its tubular form.  Seemingly simplistic at first glance, but according to Calatrava, this is a highly technical bridge.

The helical structure with glass roof and integrated linear lighting for night-time illumination, consists of about 850 metric-tonnes of steel.  Total length of the red and white bridge is 130.6 meters, with a height of 5.85 meters and a width of 6.2 meters, (3.7 meters for pedestrians and 2.5 meters for the cycle-way).

Today, this bridge is being used by approximately 6000 people a day.

The Norway Sky Bridge ~/?x=entry:entry170308-034250 2017-03-08T03:42:50+00:00 2017-03-08T03:42:50+00:00

The name of the bridge changed from “Hardanger Brigdge” to ” Norway Sky Bridge”, after seeing this photo where the construction crew walked on the walkway on the bridge suspension cables.  The rest of the bridge is shrouded in cloud, giving the appearance that the suspension cable walkway was the actual bridge.

The main span of the Bridge is 1,310 meters (4297.9 ft) – approximately 20 m longer than the Golden Gate Bridge of San Francisco. This makes the bridge the longest in Norway and 9th longest in the world.

The towers of the bridge must stand on shore due to the depth of the fjord.  The maximum water depth near the bridge is about 500 m (1,600 ft), and the mountains surrounding the fjord are about 1,200 m (3,900 ft) high.
