The record table

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

How this table is compiled

101 entries fall below a kilometre, short enough that portals and approaches usually decided their cost more than the bore itself. Morello at 5.44 km and Cannatello at 4.1 km follow it, and lengths are given per carriageway because the two bores of a dual route are rarely cut to the same length.

Also recorded here are M. Lomonaco Capo Cantoniere at 2.52 km and Imera 1 at 2.36 km. The table on this page runs to 124 rows and records Tunnel / Viaduct, Direction Catania, Direction Palermo and Notes for each of them, which is the shape the original compiler chose rather than one imposed here.

The three longest entries alone account for 16.89 km of the 69.67 km on this page, which is 24 per cent of the total from 3 of 119 rows. The shorter half of the table totals 7.87 km against 61.8 km for the longer half, from the same number of rows.

The route table lists 119 structures with a recorded length, giving both carriageways where the two bores differ. The material on this page is held in 3 captions rather than in running text, 27 words of it, each written against the image or row it belongs to by the compiler who put the page together.

This page records the structures catalogued along the A19 in Italy, in a tunnel almanac maintained at this address since the late 1990s. The captions name 5 distinct places and structures — Resuttano, Scillato and Caltanissetta among them — and those names are the index into the length tables where each is recorded with its own figure.

Reading the figures

Between the longest and the tenth-longest the drop is 5.73 km, which is the part of the table that changes when a single scheme opens. Where one of these 119 lengths disagrees with an operator's own figure for Italy, the table keeps the published value and notes the difference instead of averaging the two.

Lengths for Italy are recorded in metres which is how the operators publish them and why the shortest entry here reads as 20 m and not a rounded figure. The longest entry is 367.5 times the shortest and 27.8 times the median, which is the quickest measure of how uneven the table is.

A new scheme in Italy would have to beat 7.35 km to change the head of this table, and that is the figure worth rechecking when one opens. The eighth longest is Tremonzelli at 1.86 km, which is about where this record stops being about record holders and starts being about ordinary infrastructure.

On 23 of the structures here the two carriageways are not the same length, which is why the archive records each direction separately rather than one figure per crossing. The route crosses 4 provinces, recorded in the note column by their vehicle-registration codes (CL, CT, EN, PA), which is how the operator identifies a section.

The next two longest are Morello at 5.44 km and Cannatello at 4.1 km. A tunnel list for Italy reads differently from a neighbouring country's: 4 of these 119 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.
