The record table

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

How this table is compiled

Lengths for Argentina are recorded in metres which is how the operators publish them and why the shortest entry here reads as 46 m and not a rounded figure. The longest entry is 67.0 times the shortest and 6.8 times the median, which is the quickest measure of how uneven the table is.

Dated entries run from 1886 to 1998, and the busiest decade is the 1880s with 1 recorded openings. The material on this page is held in 8 captions rather than in running text, 61 words of it, each written against the image or row it belongs to by the compiler who put the page together.

Roughly 0 of the dated entries opened in this century, which is a rough measure of how much of the network is recent. The captions name 11 distinct places and structures — Buenos, Aires and Argentina among them — and those names are the index into the length tables where each is recorded with its own figure.

Dates for Argentina refer to opening to traffic, not breakthrough, so the 1886 entry was under construction for some years before that. Laid end to end the entries on this page would run 6.8 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued.

The table on this page runs to 24 rows and records C.P., Province, Main Town and Reg for each of them, which is the shape the original compiler chose rather than one imposed here. Rows are ordered by length, longest first, so the head of the table answers the question most readers arrive with.

Reading the figures

The table below lists 8 entries with a recorded length, each giving a name, a length in metres and, where documented, the year of opening. A new scheme in Argentina would have to beat 3.08 km to change the head of this table, and that is the figure worth rechecking when one opens.

One of those 8 is recorded as under construction or planned, Agua Negra at 13.9 km, so the count includes it while every measured figure — the range, the median, the total — describes the 7 rows carrying traffic today: an unopened bore cannot hold a record. Road tunnel lengths are measured portal to portal along the carriageway.

The longest entry is Cristo Redentor, at 3.08 km, opened in 1980. A tunnel list for Argentina reads differently from a neighbouring country's: 1 of these 7 structures pass three kilometres, and the same journey time is bought with one long bore in one country and a dozen short ones in another.

The entries sum to roughly 6.8 km of bore, an average of about 0.97 km each, though that average describes no actual row. The province column names 24 distinct entries on this page, Buenos Aires and Catamarca among them, each traceable to the operator or administration record it was taken from.

This page records the road tunnels catalogued for Argentina in a tunnel almanac maintained at this address since the late 1990s. Second and third place go to Raul Uranga at 2.4 km and Las Cuevas at 0.45 km. Further down the table, Libertador is recorded at 0.2 km and Carranza at 0.18 km.
