Tunnels on the A1 in Switzerland: Geneva to St Margrethen

150 rows are rendered in total, so 106 of them carry a note or a blank where a length belongs and are shown without being counted. The middle half of the table runs from 0.4 km to 1.21 km, and that band is where most of the engineering on this page actually sits.

The median entry measures 0.55 km, so half the table sits below that and half above, which is a better guide to the typical structure here than the headline figure. The shortest recorded entry is 0.11 km against 3.23 km at the top, a spread of 28.84x across the same table.

32 entries fall below a kilometre, short enough that portals and approaches usually decided their cost more than the bore itself. Pomy at 3.01 km and Arrisoules at 2.99 km follow it, and lengths are given per carriageway because the two bores of a dual route are rarely cut to the same length.

How this table is compiled

The route table lists 44 structures with a recorded length, giving both carriageways where the two bores differ. The material on this page is held in 18 captions rather than in running text, 140 words of it, each written against the image or row it belongs to by the compiler who put the page together.

Also recorded here are Orbe at 2.08 km and Vernier at 1.94 km. A tunnel list for Switzerland reads differently from a neighbouring country's: 2 of these 44 structures pass three kilometres, and the same journey time is bought with one long bore in one country and a dozen short ones in another.

The longest stands 0.23 km clear of the next longest, which is the margin to watch when a new scheme is announced. The captions name 46 distinct places and structures — Zurich, Ecublens and Nord among them — and those names are the index into the length tables where each is recorded with its own figure.

The three longest entries alone account for 9.22 km of the 39.06 km on this page, which is 24 per cent of the total from 3 of 44 rows. 22 entries sit above the median and 22 at or below it, so the table is evenly weighted and not clustered at one end.

Between the longest and the tenth-longest the drop is 1.86 km, which is the part of the table that changes when a single scheme opens. Where one of these 44 lengths disagrees with an operator's own figure for Switzerland, the table keeps the published value and notes the difference instead of averaging the two.

Reading the figures

Lengths for Switzerland are recorded in metres which is how the operators publish them and why the shortest entry here reads as 112 m and not a rounded figure. The longest entry is 28.8 times the shortest and 5.9 times the median, which is the quickest measure of how uneven the table is.

A new scheme in Switzerland would have to beat 3.23 km to change the head of this table, and that is the figure worth rechecking when one opens. The eighth longest is Rosenberg at 1.44 km, which is about where this record stops being about record holders and starts being about ordinary infrastructure.

Laid end to end the entries on this page would run 39.06 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued. A canal tunnel is sized by the boat, not by the traffic, which is why the oldest of them are so narrow.

The entries sum to roughly 39.06 km of bore, an average of about 0.89 km each, though that average describes no actual row. On 8 of the structures here the two carriageways are not the same length, which is why the archive records each direction separately rather than one figure per crossing.

The ten longest average 2.16 km against 0.51 km for everything below them, and that ratio is the clearest thing this table says about the distribution. 19 of them are under 500 metres, which on a route of this kind usually means a cut-and-cover section or a short spur and not a driven bore.

Questions about Switzerland

What is the longest structure in Switzerland?

On the figures recorded here it is Gubrist, at 3.23 km. It is the longest of the 44 entries recorded here, measured by bore length rather than span, cost or construction difficulty.

How many structures are listed for Switzerland?

44 entries with a recorded length appear on this page, from 0.11 km at the short end to 3.23 km at the top, with the middle of the set around 0.55 km. The table renders 150 rows in total; the rest carry a note or a blank where a length belongs.

What is a typical length among the structures listed for Switzerland?

The median entry measures 0.55 km and the middle half of the table runs from 0.4 km to 1.21 km. The headline figure of 3.23 km is the outlier, not the norm, which is why the median is the more useful number when comparing one national list against another.

How close is the top of the Switzerland table?

The longest stands 0.23 km clear of the next entry, and 3 entries sit within ten per cent of it. A newly announced scheme therefore has to beat 3.23 km to displace Gubrist.

How many structures does this route carry?

44 named tunnels and viaducts have a recorded length on this route, the longest being Gubrist at 3.23 km, followed by Pomy at 3.01 km and Arrisoules at 2.99 km; 19 of the 44 are under 500 metres.
