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

How this table is compiled

Where one of these 44 lengths disagrees with an operator's own figure for Denmark, the table keeps the published value and notes the difference instead of averaging the two. The 44 rows for Denmark are ordered by length, not by date, so the 2000 opening sits well down the table without being any less current.

Lengths for Denmark are recorded in metres which is how the operators publish them and why the shortest entry here reads as 85 m and not a rounded figure. The longest entry is 91.8 times the shortest and 21.9 times the median, which is the quickest measure of how uneven the table is.

This page records the bridges and viaducts catalogued for Denmark in a tunnel almanac maintained at this address since the late 1990s. Laid end to end the entries on this page would run 45.61 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued.

The table below lists 44 entries with a recorded length, each giving a name, a length in metres and, where documented, the year of opening. The viaduct column names 44 distinct entries on this page, Øresund bridge and Great Belt - East among them, each traceable to the operator or administration record it was taken from.

Second and third place go to Great Belt at 6.8 km and Great Belt at 6.61 km. The table on this page runs to 44 rows and records Viaduct, Length, Year of opening, Notes and Province for each of them, which is the shape the original compiler chose rather than one imposed here.

Reading the figures

Dated entries run from 1930 to 2000, and the busiest decade is the 1970s with 12 recorded openings. The material on this page is held in 5 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.

33 entries fall below a kilometre, short enough that portals and approaches usually decided their cost more than the bore itself. The year of opening column runs from 1930 to 2000 across 44 dated rows, and the 1970s alone account for 12 of them, so the building effort here came in waves rather than evenly.

A new scheme in Denmark would have to beat 7.8 km to change the head of this table, and that is the figure worth rechecking when one opens. The dated entries fall across 29 different years, which is a rough measure of whether this was a sustained programme or a handful of separate schemes.

The dated entries carry 29 distinct opening years across 70 years, and the median opening year is 1971. Read down the length column, the 44 values run from 85 m to 7 800 m with a midpoint at 356 m; the spread rather than the maximum is what says how uneven this set is.

Eighth on the list is Ny Lillebælt bro at 1.7 km, which is where the table stops being about record holders and starts being about ordinary infrastructure. The ten longest average 3.41 km against 0.34 km for everything below them, and that ratio is the clearest thing this table says about the distribution.
