The Delta Optimist has published a letter that really should have been their big headline. But never mind~Price Tags Vancouver will do it. We all remember the defeated Liberal government’s bandying around of the proposed multi-billion overbuilt Massey Bridge which would have provided ten lanes on the bridge and led to the industrialization of that part of the Fraser River. The ex premier of the province, Ms. Clark actually got on the podium and when asked during the election why this unsustainable bridge to congestion on each side of it was being built, happily announced “JOBS!”.
It turns out that despite what the past Provincial Liberal government said to the public and continually announced, there was another option to the building of this billion dollar bridge behemoth. Specialists from the Netherlands prepared a presentation~on twinning the existing tunnel in 2013. The Massey Tunnel is named after Douglas Massey’s father, and it was Mr. Massey who made a Freedom Of Information request to the then Provincial Liberal government. That turned up nothing. But a more recent repeated request turned up this Dutch Engineering twin tunnel study and it is publicly available courtesy of the new Transportation Minister, Claire Trevena.
As Mr. Massey wrote in the Optimist: “ A meeting was held on April 4, 2013 between the Ministry of Transportation and Tunnel Engineering Consultants (TEC) of the Netherlands to update the ministry on the state of the art of immersed tunneling.
The content of the 60-page presentation included introduction of TEC worldwide tunnel projects both recent and proposed, and cost-effective options for the George Massey Tunnel. Special attention was given to tunnel safety, earthquake resistance design and comparison with bridge solutions.
The following are quotes taken from that presentation:
1.Tunnels are more suited for various and poor soil conditions.
2. Tunnels are shorter in length than a bridge and have a smaller footprint.
3.Tunnels can be built parallel and close to existing tunnels.
4.Tunnel construction is capable of dealing with severe seismic conditions.
5.Tunnel construction where 80 to 90 per cent of the work could be done by local contractors.
6.Tunnels can be built “safer than an open highway.”
This Dutch team also recommended that they assess the structure and integrity of the current tunnel and increase river depth by using an asphalt mattress instead of riprap. They suggested using longitudinal ventilation and repurpose the existing ventilation ducts as escape pods and for conduits for cyclists and walkers, among other innovative ideas. This report was never made public. As Mr. Massey states ” the former Liberal government never revealed the true facts or alternatives to the public. Instead, it followed the demands of the Port of Vancouver and wrote fear mongering reports that suited its agenda of removing the George Massey Tunnel and deepening the lower Fraser River to suit present and future industrial interests.”
The Dutch have been creating these types of submerged tunnels successfully for years. Looking at twinning the tunnel would preserve the existing habitat and ecosystem of the Fraser, and restrain the industrialization of this sensitive bog and marshland. Why was this report not released before to the public? And is this a viable option for creating more capacity crossing the Fraser River?
As Mr. Massey summarizes that this sensitive area is “known the world over as vital component for a continued healthy ecosystem that supports a migratory food source for all marine and wildfowl life from the headwaters of the Fraser River along migratory routes of the Pacific Coast. May the true facts be known.”
