The record table

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

How this table is compiled

The three longest entries alone account for 8.87 km of the 117.09 km on this page, which is 8 per cent of the total from 3 of 379 rows. The shorter half of the table totals 16.14 km against 100.95 km for the longer half, from the same number of rows.

The route table lists 379 structures with a recorded length, giving both carriageways where the two bores differ. The table on this page runs to 425 rows and records Tunnel / Viaduct, Direction Reggio C., Direction Fisciano and Notes for each of them, which is the shape the original compiler chose rather than one imposed here.

Between the longest and the tenth-longest the drop is 2.28 km, which is the part of the table that changes when a single scheme opens. Where one of these 379 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.

This page records the structures catalogued along the A02 in Italy, in a tunnel almanac maintained at this address since the late 1990s. The captions name 23 distinct places and structures — Calabria, Villa and Giovanni among them — and those names are the index into the length tables where each is recorded with its own figure.

Also recorded here are Costa Incoronata at 1.81 km and Costiera di Pizzo at 1.8 km. The material on this page is held in 11 captions rather than in running text, 86 words of it, each written against the image or row it belongs to by the compiler who put the page together.

Reading the figures

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 193.8 times the shortest and 23.3 times the median, which is the quickest measure of how uneven the table is.

A new scheme in Italy would have to beat 3.88 km to change the head of this table, and that is the figure worth rechecking when one opens. The eighth longest is Casalbuono at 1.73 km, which is about where this record stops being about record holders and starts being about ordinary infrastructure.

The note column places the route in Campania, and the administrative area is recorded because a section is identified by it. Read down the direction fisciano column, the 372 values run from 10 to 3 868 with a midpoint at 158; the spread rather than the maximum is what says how uneven this set is.

The next two longest are Barritteri at 2.61 km and Iannello at 2.34 km. A tunnel list for Italy reads differently from a neighbouring country's: 1 of these 379 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 117.09 km of bore, an average of about 0.31 km each, though that average describes no actual row. On 157 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.
