Tunnels elsewhere not prohibitive
European, Asian, Aussie examples of infrastructure abound

Choked for years with traffic and pollution problems from 6,000 large freight trucks per day travelling back and forth to the city's bustling port, Dublin recently opened the longest city road tunnel in Europe.
The 4.5-kilometre tunnel will carry mostly trucks from the port and under the city to the M50 roadway. The trip used to take vehicles more than half an hour to travel the short distance because of countless traffic lights and gridlock, but will now take just six minutes to complete in the tunnel.
"Today, as we face into the 21st century, we are building 21st-century infrastructure -- and world class infrastructure at that -- in our own country, for our own people, with our own resources," said Irish Prime Minster Bertie Ahern.
Windsor's residents affected by thousands of border-crossing big rigs driving back and forth from the Ambassador Bridge have been demanding the same type of 21st-century solution -- many demanding a tunnel under this city to bury traffic.
$300M PER KILOMETRE
The binational Detroit River International Crossing (DRIC) team assigned to fix Windsor's border traffic troubles originally projected tunnel costs in Windsor ranging from $100 million to $300 million per kilometre.
But that figure ballooned this month to more than $600 million, according to data DRIC released this month.
DRIC has blamed it on the city's poor soil conditions and high water table. Those costs are comparable to the Chunnel -- the world's most expensive tunnel at C$690 million per kilometre.
DRIC has also claimed a tunnel here will do little to reduce diesel pollutants from trucks, so it can be easy to dismiss a tunnel locally (up to six kilometres in length) to handle border traffic.
But taking a quick look at what's happening elsewhere in Europe, Asia or Australia despite soil or dense urban conditions -- and often for relatively low costs -- the question again becomes why not here?
More than 5,000 people were involved in the Dublin construction effort which began in June 2001 with the official opening Dec. 20. The final project cost was C$1.15 billion, including land acquisition and design.
Heavy trucks in Dublin will use the tunnel for free, while cars and light commercial vehicles will be charged a toll. About 420 cameras will be used for safety.
Elsewhere, recent costs for tunnels have ranged from $10 million per kilometre for Norway's 24.5-kilometre Laerdal Tunnel up to the what's widely recognized as the world's most difficult construction project, the Channel Tunnel (Chunnel) linking Great Britain and France.
1,000 VEHICLES PER DAY
The Laerdal cuts through a mountain in Norway and opened in 2000. It handles only about 1,000 cars and trucks per day between Oslo and Norway's second largest city, the western port of Bergen.
The relatively new 19-kilometre Vereina Tunnel is among several railway and road tunnels in Switzerland. Opened in 1999, it cost $24 million per kilometre to build.
The Brenner Base Rail Tunnel project is listed as the top priority project of the European transport network. It will consist of a 56-kilometre twin-tube tunnel between Austria and Italy with a scheduled opening of 2009. The total cost is estimated at C$6.87 billion.
The longest underground road tunnel in Asia and fifth longest in the world opened this June in Taiwan.
The Hsuehshan (or Snow Mountain) tunnel is nearly 13 kilometres long. The tunnel cost nearly $2 billion, connecting the capital, Taipei to the county of Ilan and will cut travel time from more than two hours to 30 minutes.
There are several large city tunnels in the U.S., the largest being the 4.2-kilometre Ted Williams tunnel in Boston, part of its massive $14.6 billion Big Dig project -- the largest public works construction project in U.S. history.
Not far away is Virginia's 28-kilometre Chesapeake Bay Bridge and Tunnel, whose southbound route opened in 1999 after four years of construction at a cost of $250 million. No tax dollars were used with funding raised through sale of revenue bonds for the world's largest bridge-tunnel complex.
