A Bridge in Disassembly - Vancouver, BC

The Port Mann Bridge that connects the Lower Mainland of Vancouver with the Fraser Valley is getting the slow demolition treatment.

The old bridge on the right is being disassembled. The exposed concrete support now shows under the orange and yellow equipment in the image, since one large section has been removed. Construction on the original Port Mann Bridge began in 1957, was completed in 1964, and closed in 2012. The new bridge has greater capacity, and a more efficient design including an HOV lane. Tolls for most cars are $3 each way. Free old bridge to tolled new bridge, we will go from six lanes to ten when all are completed. There are still  bridge construction 'holdups' at various times, a part of life in the big city.

The upright supports on the right of the image are loosely strung with cables and form part of the equipment used in stripping the road surface and removing the orange girders. Not sure if any of the bridge pieces are being recycled for another use. Perhaps that explains the slow demo, aside from the reality of those guys working over deep water, the Fraser River.

Shown below is a section of the old bridge with the supports which are assisting in the dismantling or disassembly of the roadway and the arching orange girders. Orange made the bridge more visible on those gray wet days that we get in Vancouver, aka rainforest country.

It's interesting to watch the process when something is being dismantled, as opposed to being demolished. Bridges spanning large rivers or small water sources are one of the things I like about both Vancouver and Paris.

Happy St. Patrick's Day, if you indulge. And watch out for the greenies. . .
