Gord Henderson's response to the above:
Tunnelling worth it

The game plan is obvious. Whack Windsorites between the eyes with a mind-boggling price tag and then stand back and watch as support for a world-class border solution melts like a snow cone on hot asphalt.
The $3.8-billion estimate for tunnelling six kilometres of the Huron Church Road corridor, disclosed Wednesday by the Detroit River International Crossing (DRIC) study team, is clearly intended to undermine this community's passionate commitment to a tunnelled truck route.
Rolled out in tandem with preliminary air pollution numbers compiled by consultants, which suggest tunnelling might actually worsen our air quality, and you've got a one-two punch meant to bring city residents to their knees.
Initially at least, it appeared to be working, with people attending the DRIC dog-and-pony show at the Holiday Inn Select -- quite the costly spectacle with its fruit and pastry trays and banks of giant flat-screen TVs -- shaking their heads and gasping in amazement that their preferred solution could cost more than paving Huron Church in gold.
No question about it. The DRIC's tunnel tag is astonishing. At $3.8 billion (in 2011 dollars) for six kilometres, it works out to something like $633,000 per metre. Or more than $16,000 per linear inch.
It makes one wonder. How did they arrive at that figure? Did they pump the numbers to produce terminal sticker shock? Did they have instructions from their political masters in Ottawa and Toronto to throw in everything but the kitchen sink and build the worst case scenario? If they were cautioning us last year that a tunnel could cost as much as $2 billion, how did it almost double?
LOUSY SOIL
Blame it on your lousy wet soil and a high water table, said one of the project engineers. He told me the soft, silty sand rules out boring a tunnel and makes a cut-and-cover tunnel a massive, time-consuming project. He described how caissons (steel I-beams filled with concrete) 1.5 to two metres in diameter would have to be pounded deep into the ground two to three metres apart for the whole length of the tunnel. And that's just one key step in building the tunnel's retaining walls.
I got the picture. Constructing a truck tunnel would be far more complex and labour-intensive than most of us civilians imagined.
I came away with another impression. These guys are tunnel virgins. Ontario might be yours to discover but it doesn't do highway tunnels. Officials had to think hard before citing three tunnels under the Welland Canal, the most recent built in the 1960s, as examples of road tunnelling in the province. They don't know the business. And I suspect they'd like to keep it that way.
It's a damn shame because there's a wealth of tunnelling expertise in Europe which could lead them by the hand and help them overcome their bashfulness about going underground.
Last spring I described how tiny Norway has built tunnels under mountains, fjords, and ocean seabeds to link small towns and remote islands with the mainland. Norway built the world's longest highway tunnel, the 24.5 km Laerdal Tunnel on the main road between Bergen and Oslo, at a cost of roughly C$220 million in the late 1990s. And they did this in the face of daunting problems involving unstable rock formations.
Meanwhile, Sweden and Denmark built a 15-kilometre tunnel, man-made island and bridge linking their countries across the Baltic Sea's Oresund Strait at a cost of US$3.7 billion. These are pros, people with vision and daring, and they should have been recruited early in this process.
If these countries can think big, with a fraction of the trade that passes between Canada and the U.S., how can we settle for a second or third-rate solution for the world's busiest and most lucrative border crossing?
It's outrageous that the DRIC even has an at-grade alternative on the table. That's 1950s thinking, with a $920 million price tag, and it speaks volumes about their contempt for Windsor that they would list it as an option.
What's Windsor's future worth? What's Canada's trade with the U.S. worth? Is it worth a $3.8 billion, one-time investment in a tunnel that, according to the engineers, would be built to last 75 to 100 years.
In 2106 will our descendants look back on us as risk-takers with foresight -- like the folks who built the existing bridge and tunnel -- or shortsighted fools like those who decided to end the 401 at Highway 3?
Don't be cowed by sticker shock. Windsor, Ontario and Canada deserve the best permanent solution, not a cheap way out.
