This aerial photo provides a better vantage point to grasp the reason why they are excavating the east side of Johnson Hill. Looks like some excavating will also be required on the west side.

BTW, that's only 2/3 width of the new PMB deck. The old PMB needs to be removed for the remaining 1/3 decking on the third set of piers to be completed. Man, she's gonna be huge! Just compare the beefy piers against the old PMB counterparts.

The new Port Mann bridge taking shape:

PORT MANN BRIDGE/ HIGHWAY ONE PROJECT FACTS



· The new bridge will be more than two km long, have a 50-metre wide roadway surface and have a 42-metre clearance above high water level.

· The crossing will consist of a 10-lane, 850-metre cable-stayed bridge and precast concrete approaches of 1,170 metres. At 470 metres, the cable-stayed main span will be the second-longest in North America.

· 13,000 tonnes of structural steel will be used to construct the bridge.

· 1,158 precast concrete segments will be fabricated and used to build the bridge.

· A custom-made launching truss (blue and yellow gantry) is being used to install the 1,158 segments. The truss is 19 metres wide, 13 metres tall, 155 metres long and weighs 720 tonnes.

· 157,000 cubic metres of concrete will be used to construct the bridge.

· 28,000 tonnes of rebar will be used in the concrete.

· Total area of the new bridge will be 104,000 square metres.

· 25,000 tonnes of asphalt will be used for the deck riding surface.

· The bridge will be supported by 288 cables, 23 piers, two abutments, 108 drilled shafts, and 251 piles (122 land, 129 marine). There is a total length of 16 km of pile. There is a total length of 5,000 metres of drilled shafts.

· The cables will be attached to two pylon towers, each 160 m high – roughly the equivalent of a 50-storey building. The towers will stand approximately 75 metres above deck level.

Webcam pics from today - you can definitely make out 4 sleeves (tubes) where the cables will be held in place:

The highway at this point will have 5 lanes in each direction in a collector lane / express lane configuration, with 2 collector lanes, and 3 express lanes (one of which will be an HOV lane). The old bridge is 5 lanes.

It must suck walking up those tall cranes every day.

It seems like the hi-way it self is only 5 lanes anyway - what's the point in having more on the bridge?
Are they planing on expanding the hi-way possibly ?

 

[Kitsune]

Its 5 Lanes each direction, with dedicated HOV Lanes. Also, it'll allow cycling and pedestrians to cross, and there's a provision for LRT underneath the bridge.

Webcam pics from today - looks like the first segment of bridge deck is being built (as opposed to being prefabricated)

There's steel on the outriggers for the roadway on both sides of the tower now:

The gantry has started assembling the approach on the north side of the Port Mann Bridge (with active traffic below).
This segmental construction method is the same one used to assemble overhead guideways for SkyTrain.

Hello
I had a brief chance today to take some pics today in the sun.

They are not of the ramps (sorry) but it is a very cool and unique point of the project nonetheless.

Currently, the gantry crane putting together the north approach is directly overhead of the United Boulevard with many segments suspended above the traffic. Let me just say many are rubber necking it today! (Also it is scary looking through my sunroof to the concrete mass hanging above me as I wait to go on Mary Hill).

Here are my pics!

All pics my own, here in my flickr account:

The east (south) tower is now topped out (maybe there'll be a steel cap?).

AND - the first cable is up!!
- it's one of the side/lateral cables to the outrigger -
