A tunnel from just east of Elevator Road under the Annieville and Sunbury Neighbourhoods and exiting at Nordel Way and Highway 91 would resolve most of the problems with the current SFPR route - protecting the environment and reducing the neighbourhood impacts of noise and exhaust pollution.
For the past 14 months, we have been asking Gateway for a detailed analysis of the costs and benefits of a tunnel route vs their riverside route. At the end of May, 2006 they provided us with the following analysis:
In our response, we outline the gaps in their analysis:
17 in Canada including 3 in BC
121 projects in Spain, 57 in Austria, 61 France, 65 Germany...... http://www.tunnelbuilder.com/countryfiles_index.htm
Searching the tunnelling projects world wide for highways and there are a lot of them, here are what I have estimated to be the closest comparables:
So where are Mr Proudfoot's numbers? By these projects I can't see how the tunnel is out of line. We are boring through a pile of gravel with some sand and clay thrown in as adhesives. Mr. Proudfoot/Gateway should be held to bring something to the table and prove the tunnel too costly. I believe that should be part of the public consultation. Don't you?
This is interesting;
Auckland - nz/13 Second Harbour Crossing Options under study for a second harbour crossing near the Auckland Harbour Bridge, either a bridge or a tunnel under the Waitemata Harbour and tunnel connections to the north-western and south-western motorways, costing up to $2 billion. Any tunnel must fit plans for the extension of State Highway 20 through Avondale. The cheapest option is to widen or build a new viaduct. Second option is to put the motorway in a trench through Victoria Park for $220-$250 million. Third option is a partial or full tunnel under Victoria Park at a cost of $150-$290 million. The fourth option is to tunnel under Victoria Park and straighten the approach to the harbour bridge, for a cost of $350-$430 million. Interesting they choose the Tunnel, it's cheaper than the bridge!
In Tokyo a bypass tunnel on Madrid's 30 mile loop highway planned by that city's municipal government. The tunnel, scheduled to open in March 2007, is expected to help solve the chronic traffic jams, frequent accidents, noise and lack of greenery at the chosen site.
TUNCONSTRUCT, a Project to Boost the Use of Underground Space in
The utilization of underground space can have a significant impact on living conditions. For example, underground trains greatly contribute to the reduction of pollution and long base tunnels are innovative ideas for sending freight underground. It is commonly admitted that underground space is currently underused. It is possible to envisage a city of the future that has virtually no vehicle traffic above ground, thereby freeing space for parks and recreational facilities. One of the reasons that underground space is underutilised is because, as compared to above ground construction, underground construction is still too risky and expensive.
The aim of the TUNCONSTRUCT project (an acronym which stands for Technology innovation in Underground Construction) is to make underground construction significantly less risky and expensive by introducing innovative technology. The project should pave the way to the introduction of innovative solutions that have been proposed for the transport infrastructure and cities.
The integrated project TUNCONSTRUCT gathers many of the European main players in industry, research and business in a consortium of more than 30 partners from 11 countries across Europe. The planned innovations involve all aspects of underground construction and can be divided into the following areas: prediction and design; construction equipment; processes; and maintenance and repair.
