project slideshow

see how it all came together

1 / 26

The project required a large number of discrete construction stages to allow for uninterrupted traffic flow during peak daytime periods.

2 / 26

Contractor forces prepare bridge girders for concrete deck pour.

3 / 26

Excavator mounted hydraulic jaws demolish one of the existing overpasses to make room for the widened west approach to the Port Mann Bridge.

4 / 26

A number of bridges required night time lifts to minimize the impact on traffic flows during the daytime hours.

5 / 26

WSP provided both design and quality assurance during construction. WSP staff member, Vladimir Lebed, oversees the precast concrete girder erection.

6 / 26

The design called for extensive construction staging of bridges, lightweight fill embankments and retaining walls.

7 / 26

New bridge construction and demolition of existing bridges was staged to facilitate safe and undisrupted traffic flows during peak hours.

8 / 26

The sequence of work may have seemed alien to the casual observer.

9 / 26

The existing Port Mann Bridge carries traffic as the new bridge is constructed.

10 / 26

The staging of the Onshore works was coordinated with the new Port Mann Bridge construction to enable the transportation of massive precast concrete bridge segments to the erection gantry visible near top of the picture.

Neil Cumming, materials specialist. Neil provided material science and testing expertise utilized in design, inspection and quality assurance for both the Port Mann Bridge and the Onshore portion of the project.

12 / 26

A view from above. The existing Cape Horn interchange overpass was at a similar grade as the new curved ramp. The missing span was erected during a weekend when the existing structure was decommissioned and demolished.

This photo shows four of the five separate structures built over the realigned CP Rail tracks and the Lougheed Highway.

14 / 26

The Trans Canada Highway west of Gilmore Avenue. The new curved steel girder HOV ramps were built in advance of the new approach works to take advantage of larger work areas needed for bridge construction.

15 / 26

WSP employee Janet Branch was a senior design coordinator, working closely with the contractor to advance the design.

16 / 26

The project called for liaison with many stakeholders along the corridor, including the relocation of CPR tracks to accommodate the widening of the Trans Canada Highway through Coquitlam.ORSun rising over yet unfinished Cape Horn Interchange.

17 / 26

Boundary Road interchange on the Burnaby-Vancouver border. Some of the structures were rehabilitated, widened and seismically retrofitted, while others were entirely replaced.

18 / 26

Three cranes are required to lift the steel girders for a 12 span, 600m long ramp at the center of the Cape Horn Interchange.

19 / 26

Keith Holmes, a senior project manager and WSP's Project Lead, was responsible for a number of designs as well as the west segment design coordination.

20 / 26

The completed 160th Street Interchange in Surrey (East End of the project corridor).

21 / 26

A view from the top of one of the new Port Mann Bridge towers. Traffic remains on the existing structure while deck for the new Port Mann Bridge is constructed.

22 / 26

The newly completed Cape Horn interchange.

23 / 26

A view from below of the completed Lougheed Highway eastbound flyover.

24 / 26

A view looking east over part of the nearly completed new Cape Horn interchange. A large shotcrete wall enabled the shift of Lougheed Highway to the north. Sound walls were designed and installed near the top of the wall to help mitigate the impact of increased traffic volumes on near-by residents.

25 / 26

The completed Cape Horn interchange. Demolition of the existing Port Mann Bridge is underway to allow the completion of the west approach spans to the new bridge structure.
