The record table

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

How this table is compiled

Where one of these 34 lengths disagrees with an operator's own figure for Czechia, the table keeps the published value and notes the difference instead of averaging the two. The 34 rows for Czechia are ordered by length, not by date, so the 2020 opening sits well down the table without being any less current.

Lengths for Czechia are recorded in metres which is how the operators publish them and why the shortest entry here reads as 24 m and not a rounded figure. The longest entry is 265.9 times the shortest and 17.1 times the median, which is the quickest measure of how uneven the table is.

A new scheme in Czechia would have to beat 6.38 km to change the head of this table, and that is the figure worth rechecking when one opens. Eighth on the list is Klimkovice at 1.09 km, which is where the table stops being about record holders and starts being about ordinary infrastructure.

1 of the 34 measured entries exceed five kilometres, and those are the ones that carry a full ventilation and escape regime. Laid end to end the entries on this page would run 25.99 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued.

Dated entries run from 1910 to 2020, and the busiest decade is the 2000s with 11 recorded openings. The table on this page runs to 58 rows and records Tunnel, Length (m), Year of opening, Kraj and Okres for each of them, which is the shape the original compiler chose rather than one imposed here.

Reading the figures

The dated entries carry 16 distinct opening years across 110 years, and the median opening year is 2006. Read down the length (m) column, the 58 values run from 24 m to 6 382 m with a midpoint at 438 m; the spread rather than the maximum is what says how uneven this set is.

Roughly 20 of the dated entries opened in this century, which is a rough measure of how much of the network is recent. The captions name 30 distinct places and structures — City, Ostrov-Maletin and Hulin-Border among them — and those names are the index into the length tables where each is recorded with its own figure.

The earliest dated entry is Strahovsky, opened in 1997, and the most recent is Podvinny Mlyn in 2020. The material on this page is held in 31 captions rather than in running text, 233 words of it, each written against the image or row it belongs to by the compiler who put the page together.

They are not uniform: the fullest runs to 18 words and the briefest to 6, and on a page of this kind the long ones are where the explanation lives — the caption carries what the picture cannot. Ventilation and escape provision, not bore length, drive most of the cost on modern road tunnels in Czechia.

Second and third place go to Panenska at 2.17 km and Strahovsky at 2 km. 57 of the 58 rows carry an entry in the notes column — 98 per cent of the table — and that column is where the qualifications live: tube counts, closures, boundaries and the reason a figure reads the way it does.
