The record table

How this archive measures: lengths, bores, dates and ordering

How this table is compiled

The three longest entries alone account for 0.73 km of the 21.61 km on this page, which is 3 per cent of the total from 3 of 179 rows. After the 1990s the next busiest decade here is the 1980s with 31 openings, so the building effort came in more than one wave.

Where one of these 179 lengths disagrees with an operator's own figure for Austria, the table keeps the published value and notes the difference instead of averaging the two. The 179 rows for Austria are ordered by length, not by date, so the 2010 opening sits well down the table without being any less current.

Lengths for Austria are recorded in metres which is how the operators publish them and why the shortest entry here reads as 13 m and not a rounded figure. The longest entry is 19.0 times the shortest and 2.2 times the median, which is the quickest measure of how uneven the table is.

The longest stands 0 km clear of the next longest, which is the margin to watch when a new scheme is announced. Laid end to end the entries on this page would run 21.61 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued.

The table below lists 183 entries with a recorded length, each giving a name, a length in metres and, where documented, the year of opening. The tunnel column names 181 distinct entries on this page, Hebesberger UT (Rossleithen) and Hausberg (Gratkorn) among them, each traceable to the operator or administration record it was taken from.

Reading the figures

This page records the road tunnels catalogued for Austria in a tunnel almanac maintained at this address since the late 1990s. The date of opening column runs from 7 to 2010 across 107 dated rows, and the 1990s alone account for 23 of them, so the building effort here came in waves rather than evenly.

Further down the table, Göming UT is recorded at 0.24 km and Schillerpark UT at 0.24 km. Read down the length (m) column, the 183 values run from 13 m to 247 m with a midpoint at 110 m; the spread rather than the maximum is what says how uneven this set is.

Dated entries run from 1856 to 2010, and the busiest decade is the 1990s with 33 recorded openings. The table on this page runs to 183 rows and records Tunnel, Length (m), Date of opening, Land and Bezirk for each of them, which is the shape the original compiler chose rather than one imposed here.

A new scheme in Austria would have to beat 0.25 km to change the head of this table, and that is the figure worth rechecking when one opens. The dated entries fall across 45 different years, which is a rough measure of whether this was a sustained programme or a handful of separate schemes.

The dated entries carry 45 distinct opening years across 154 years, and the median opening year is 1985. The material on this page is held in 6 captions rather than in running text, 59 words of it, each written against the image or row it belongs to by the compiler who put the page together.
