Gotthard Base 35.4-mile rail tunnel

The world's longest tunnel will be created tomorrow when a massive drilling machine breaks through the last few inches of rock underneath the Alps.

The 35.4-mile Gotthard Base rail tunnel is being hailed as an environmental triumph as much as an unprecedented engineering feat.

The €8bn hole through the Gotthard massif, including the 8,200-foot Piz Vatgira, along the route to Italy is part of a larger project to shift goods from roads to rails, spurred mainly by a concern that heavy trucks were destroying Switzerland's Alpine landscape.

Swiss voters, who are paying around €900 each to fund the project, approved its construction in a series of referendums almost 20 years ago and will have to wait several more before it is ready for rail traffic.

Conservationists say the money was worth spending even if it will only shave one hour off the time trains travel between northern Europe and Italy.

"The Swiss love their mountains," said Thomas Brolli a former journalist and campaigner with the group Alpen-Initiative, which claimed a surprise victory in 1994 with a referendum to limit the number of heavy goods trucks allowed to cross the Alps each year to 650,000 - halving the current load - within two years of the tunnel's opening.

"Every Swiss has a link to the Alps, whether they were born there or go there on holiday," he said.

Some 1.2 million trucks currently thunder through Switzerland's countryside every year, harming rare plants and animals while adding to the erosion that is the Alps' worst enemy.

With their beloved mountains crumbling, the Swiss decided that instead of simply stopping foreign trucks from passing through the country they would put their tunnel-building expertise to good use by completing a plan first conceived more than 60 years ago.

When it is opened for traffic in 2017, the Gotthard Base Tunnel will supplant Japan's 33.5-mile Seikan Tunnel as the world's longest - excluding aqueducts - and allow millions more tons of goods to be transported quickly through the Alps by rail.

A further €11.5bn is being spent on a series of shorter tunnels and high-speed rail links that will ultimately allow high-speed trains from Germany to continue on through to Italy at up to 155 miles an hour, making rail journeys increasingly economically competitive.

For European transport ministers, who will be watching the breakthrough ceremony live from a meeting in Luxembourg, the project represents the first of a series of major rail tunnels meant to take the strain off congested Alpine road links.

A second would connect Lyon, France, to Turin in Italy, while a third would largely replace the Brenner road tunnel between Austria and Italy - currently one of the main transport arteries through the Alps.

Those projects are still a long way from completion and could yet be derailed by spending cuts as European governments scramble to fill holes in their budgets rather than drill new ones into the mountains.

Although Switzerland has weathered the financial crisis better than most of its neighbours, cost considerations might have tipped the scales had there not been a strong concern for the future of the mountains.

"I am full of admiration for the Swiss ability to combine a modern advanced economy with pristine Alpine beauty, even when it is expensive to do so," said Jeffrey Frankel, an economics professor at Harvard and former Clinton adviser. "I suspect no other country would have paid for this project."

Green ideas were inserted at every step of the tunnelling process.

Some of the 459 million cubic feet of rock hewn from the mountain - enough to fill 13 Empire State buildings - are being used to restore Alpine lakes that were dredged for gravel.

Feckin Examiner. Should have defined that in units of (Cork) County Halls.
