How this table is compiled

The three longest entries alone account for 57.67 km of the 482.57 km on this page, which is 12 per cent of the total from 3 of 57 rows. The shorter half of the table totals 180.56 km against 302.01 km for the longer half, from the same number of rows.

Where one of these 57 lengths disagrees with an operator's own figure for China, the table keeps the published value and notes the difference instead of averaging the two. The 57 rows for China are ordered by length, not by date, so the 2025 opening sits well down the table without being any less current.

A new scheme in China would have to beat 22.13 km to change the head of this table, and that is the figure worth rechecking when one opens. The longest entry is 3.7 times the shortest and 3.2 times the median, which is the quickest measure of how uneven the table is.

57 of the 57 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 482.57 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued.

Further down the table, Xishan is recorded at 13.65 km and New Erlangshan at 13.43 km. The table on this page runs to 81 rows and records Tunnel, Length (m), Date of opening, Province and Notes for each of them, which is the shape the original compiler chose rather than one imposed here.

Reading the figures

The ten longest average 14.66 km against 7.15 km for everything below them, and that ratio is the clearest thing this table says about the distribution. The tunnel column names 79 distinct entries on this page, Chagangliang and Zhongnanshan among them, each traceable to the operator or administration record it was taken from.

Dated entries run from 2006 to 2025, and the busiest decade is the 2010s with 34 recorded openings. The material on this page is held in 67 captions rather than in running text, 534 words of it, each written against the image or row it belongs to by the compiler who put the page together.

Roughly 56 of the dated entries opened in this century, which is a rough measure of how much of the network is recent. The captions name 55 distinct places and structures — Expressway, Expw and Hefen among them — and those names are the index into the length tables where each is recorded with its own figure.

The dated entries carry 13 distinct opening years across 19 years, and the median opening year is 2011. They are not uniform: the fullest runs to 29 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.

Second and third place go to Zhongnanshan at 18.04 km and Jingpingshan at 17.5 km. Read down the length (m) column, the 81 values run from 6 005 m to 22 600 m with a midpoint at 7 120 m; the spread rather than the maximum is what says how uneven this set is.
