The record table

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

How this table is compiled

Where one of these 8 lengths disagrees with an operator's own figure for Peru, the table keeps the published value and notes the difference instead of averaging the two. The 8 rows for Peru are ordered by length, not by date, so the 1958 opening sits well down the table without being any less current.

Lengths for Peru are recorded in metres which is how the operators publish them and why the shortest entry here reads as 119 m and not a rounded figure. The longest entry is 6.1 times the shortest and 2.2 times the median, which is the quickest measure of how uneven the table is.

Dates for Peru refer to opening to traffic, not breakthrough, so the 1940 entry was under construction for some years before that. Laid end to end the entries on this page would run 2.8 km, which is a number with no engineering meaning but a useful sense of the scale of what is catalogued.

This page records the road tunnels catalogued for Peru in a tunnel almanac maintained at this address since the late 1990s. The table on this page runs to 24 rows and records 2nd, Department and Main Town for each of them, which is the shape the original compiler chose rather than one imposed here.

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 fault zone crossed at an angle is longer to pass through than the same fault crossed square, which is why alignments bend for reasons the map does not show.

Reading the figures

The entries sum to roughly 2.8 km of bore, an average of about 0.35 km each, though that average describes no actual row. A new scheme in Peru would have to beat 0.73 km to change the head of this table, and that is the figure worth rechecking when one opens.

Eighth on the list is del Portillo at 0.12 km, which is where the table stops being about record holders and starts being about ordinary infrastructure. The department column names 24 distinct entries on this page, Tumbes and Piura among them, each traceable to the operator or administration record it was taken from.

Second and third place go to Impertinente at 0.41 km and Cahuish at 0.41 km. A tunnel list for Peru reads differently from a neighbouring country's: 0 of these 8 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 longest entry is Infiernillo, at 0.73 km, opened in 1958. Further down the table, Camana is recorded at 0.28 km and Santa Cruz at 0.25 km. 3 of the 8 entries fall within a quarter of the median length, which is how tightly this particular list clusters around its typical structure.

Dated entries run from 1940 to 1958, and the busiest decade is the 1950s with 5 recorded openings. Roughly 0 of the dated entries opened in this century, which is a rough measure of how much of the network is recent. Road tunnel lengths are measured portal to portal along the carriageway.
