2009 Golden Ears Extradosed Bridge over Fraser River in Vancouver Metro Area

(Bridge Hunter broke Mar 23, 2023; Satellite)

I first noticed the golden cylinders.  Then I noticed the two birds at the top of the first tower. There are four, relatively short, towers on this bridge. I thought maybe it was an extradosed bridge like the Mississippi River bridge at Sillwater, MN. In fact, it is called the "longest extradosed bridge in North America." [sefindia]

"The extradosed bridge incorporates three main spans, each 244 m [800'] long and two shoreline spans, each 122 m [400'] long for total length of 976 m. Eight pylons are situated in the river, 4 of which are 90 m [295'] high."

It cost $808m.
"The main challenge for the construction team was the development of large-diameter bored piles for the foundations to protect the soft silt layers of Fraser River and to save costs....The bridge has 160 stay cables of 20cm with more than 50 strands each to hold the deck in place."
