How this table is compiled

Where one of these 63 lengths disagrees with an operator's own figure for Bosnia and Herzegovina, the table keeps the published value and notes the difference instead of averaging the two. The shorter half of the table totals 4.1 km against 24.46 km for the longer half, from the same number of rows.

Lengths for Bosnia and Herzegovina are recorded in metres which is how the operators publish them and why the shortest entry here reads as 22 m and not a rounded figure. After the 2010s the next busiest decade here is the 1980s with 2 openings, so the building effort came in more than one wave.

This page records the road tunnels catalogued for Bosnia and Herzegovina in a tunnel almanac maintained at this address since the late 1990s. A new scheme in Bosnia and Herzegovina would have to beat 2.94 km to change the head of this table, and that is the figure worth rechecking when one opens.

The table below lists 63 entries with a recorded length, each giving a name, a length in metres and, where documented, the year of opening. The tunnel column names 63 distinct entries on this page, Vijenac / 1 Mart and Suhodol / 25 Noveml among them, each traceable to the operator or administration record it was taken from.

Further down the table, Vranduk 1 is recorded at 1.01 km and Stambolcic at 0.95 km. Read down the length (m) column, the 63 values run from 22 m to 2 942 m with a midpoint at 300 m; the spread rather than the maximum is what says how uneven this set is.

Reading the figures

The longest entry is Vijenac / 1 Mart, at 2.94 km, opened in 2014. 45 of the 63 rows carry an entry in the notes - section column — 71 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.

Dated entries run from 1983 to 2017, and the busiest decade is the 2010s with 16 recorded openings. The material on this page is held in 13 captions rather than in running text, 124 words of it, each written against the image or row it belongs to by the compiler who put the page together.

Roughly 16 of the dated entries opened in this century, which is a rough measure of how much of the network is recent. Laid end to end the entries on this page would run 28.56 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued.

The longest stands 0.14 km clear of the next longest, which is the margin to watch when a new scheme is announced. Only 18 of the 63 rows carry anything in the date of opening column, so that field describes a minority of this table and the rest of the rows are recorded without it.

58 entries fall below a kilometre, short enough that portals and approaches usually decided their cost more than the bore itself. The captions name 20 distinct places and structures — Tarcin, Sarajevo and Karuše among them — and those names are the index into the length tables where each is recorded with its own figure.
