Some public works justify themselves. A bridge where people already cross every day, a third lane where traffic already jams: the spreadsheet balances before the first machine arrives. The Carretera Austral was never one of those. It is a 1,058-kilometer road cut through fjords, glaciers and channels to reach a territory where fewer than one person lives per square kilometer. That figure sits alongside another one repeated everywhere, the 1,240 kilometers of the scenic corridor the State declared in 2024: they measure different things, and further down we separate one from the other. No ordinary cost-benefit calculation recommended opening it. It was opened anyway. Today 614.5 of those kilometers are paved, and the State has just multiplied by 5.7 what it invests every year in the ones still missing.

It is worth looking at Norway before drawing conclusions about the gravel. The E39 links Kristiansand and Trondheim along the Norwegian west coast for roughly 1,100 kilometers, almost exactly the length of Route 7, which is the name the Carretera Austral carries in the State road network, the one that appears on the blueprints and in the decrees. Norway is one of the richest countries on the planet, and its fjord trunk road still takes about 21 hours to drive, with 7 ferry crossings embedded in the route. Statens vegvesen, the Norwegian Public Roads Administration, runs a program called Ferjefri E39 to remove those seven ferry legs with submerged tunnels, floating bridges and fjord crossings, aiming to cut travel time in half. A fjord does not ask how much the country crossing it earns.

Placed side by side, the two roads do not form a ranking: they explain each other. They measure different things because they face the same geographic accident from two different engineering traditions.

The table does not add up its columns, and it should not. Norway measures continuity and travel hours, Chile measures paved surface. What is comparable is the obstacle: a broken coastline, water in the middle, scattered population and a long-term state decision to solve it. That a country with Norway's income is still wrestling with seven ferry crossings on its trunk road says a great deal about the cost of taming a fjord.

Before going further, a second figure needs fixing, because it measures something else. On December 30, 2024, at Cerro Castillo National Park, the Directorate of Roads signed the declaration defining the Carretera Austral as a scenic route: 1,240 kilometers of Route 7 between Puerto Montt and the junction with Route X-91, plus 7 kilometers of that same X-91 up to Puerto Bahamondes, 1,247 in total, spread over 10 sections, 15 municipalities in the Los Lagos and Aysén regions and 14 protected wild areas. It is the longest declared scenic route in the country. Those 1,240 declared kilometers are not the same as the 1,058 kilometers of road: the first is the corridor the State recognizes as scenic, the second is the road between Puerto Montt and Villa O'Higgins, and it is over those 1,058 kilometers that every paving percentage below is calculated.

614.5 Kilometers of Asphalt and 443.5 Still on Gravel

The work has a builder with a name. The Chilean Army's Military Labor Corps was created in 1953 and began work on Route 7 in Puerto Montt in 1976. By 2023 it had advanced 1,215 kilometers on the Carretera Austral, as far as Punta Pisagua in the Aysén Region, equal to 66% of all works on the road, within 1,877 kilometers of roads built by that unit across the country. That 1,215 measures kilometers of works executed, not length of alignment: that is why it exceeds the 1,058 kilometers of road even though the works reached Punta Pisagua and not Villa O'Higgins. Half a century of the same unit doing the same job in the same place.

Opening a road down there is nothing like opening one in the central valley. Every kilometer crosses rock, peat, meltwater rivers and slopes that move, and much of the alignment runs through places where the only alternative to the road is the sea. It is the same tradition of applied engineering that shows up whenever the terrain hands us a problem the manual does not cover, the same one behind the seismic code that keeps buildings standing in one of the world's most earthquake-prone countries. Here the enemy does not shake: it rains, freezes and crumbles.

The state of the road surface is certified by the Directorate of Roads of the Ministry of Public Works, the agency that manages the route. The exact number matters, because for years it circulated secondhand.

58% of 1,058 kilometers. That leaves 443.5 kilometers still on gravel, with everything that implies: speeds of 40 or 50 kilometers per hour, tires that last half as long, ambulances that take twice the time, trucks carrying less than they could. In a territory like this, asphalt is not a comfort. It is the difference between being connected and being close to it.

The Aysén Region covers 108,494.40 square kilometers, 14.3% of Chile, with a density of 0.93 inhabitants per square kilometer. Every paved kilometer there costs the same as anywhere else in the country and serves fewer people than anywhere else. That is why each one weighs so much.

The route is not a finished work being maintained either: it is a work still under construction, and its chronology shows that better than any adjective.

Seventy-three years separate the creation of the Military Labor Corps from the plan that now funds the continuation of its work. In that span, governments changed, machines changed, even the way the work is measured changed, and the alignment kept moving south. Few Chilean public policies have that kind of continuity. This one does, because it never depended on a single announcement.

800,393 Million Pesos and Six Dollars Back for Every One

On April 30, 2026, the Ministry of Public Works announced the Ruta Austral Plan 2026-2030, a special investment program worth 800,393 million pesos: 758,858 million from the ministry itself and 44,940 million from the Aysén Regional Government through the National Regional Development Fund. There are 23 integrated projects. Twenty are road projects and include 150.4 kilometers of definitive paving, 93.6 kilometers of basic asphalt and two new bridges over the Palena and Rosselot rivers, replacing suspension structures more than 30 years old. The other three are maritime and lake projects and add two new barges, because in Patagonia the road sometimes floats. The plan's most concrete target is to fully pave the 658.3-kilometer corridor between the northern regional boundary of Aysén and Lago Juncal, in Cochrane, working on the 244 kilometers of gravel remaining in that stretch. Planning infrastructure over five years and delivering it is a muscle we have trained before, the same one that built the second-largest metro network in Latin America line by line over half a century.

That said, the headline amount says less than it seems. What changes the order of magnitude is the pace.

Between 2016 and 2025, the State invested an average of 24,353 million pesos a year in Route 7. Between 2026 and 2030 it will invest 139,902 million pesos a year, 5.7 times more on the same corridor. This is not a budget increase, it is a change of scale. A road that advanced at the speed of whatever the treasury had available now advances at the speed of a plan with a deadline.

The obvious question is what all of that gives back. Route 7 is the northern road spine of a system of 17 national parks stretching 2,800 kilometers between Puerto Montt and Cape Horn, with 11.8 million protected hectares and more than 60 neighboring communities; those 17 parks hold 91% of Chile's national park territory. A study published in July 2026 by Fundación Rewilding Chile and McKinsey & Company measured how much returns to the local economy for every public peso placed there.

Six dollars for every dollar in 2024, with a projection of 8.6 by 2030. The detail is just as telling: 560,000 visitors, an all-time record and 15.3% above pre-pandemic levels, and USD 155 million in revenue. International visitors are 47% of the total and contribute 72% of that revenue, spending an average of 93,159 pesos a day against 39,133 for domestic visitors. It is worth stating precisely: the measurement comes from a private foundation and a private consultancy, not from an official State figure. It is, however, the best evidence available, and it points in a clear direction. The road is not spending. It is capital.

Nine Out of Ten Beds Taken While the Country Dipped

Demand is not a 2030 projection, it is already on the road. Between December 2025 and March 2026, an estimated 229,947 visitors came to the Aysén Region. Arrivals at lodging establishments grew 7.1% while the national figure fell 2.5%, according to SERNATUR using the National Statistics Institute's monthly tourist accommodation survey. Regional hotel occupancy reached 76.8% in January and 75.7% in February. And at the heart of the route the number jumped.

89.9% occupancy in February 2026 in the Coyhaique-Puerto Aysén destination, first place nationwide, ahead of any seaside summer resort. In the middle of summer, there were almost no beds left at kilometer zero of Chilean Patagonia. That result does not appear by chance in the country's least populated region, and it speaks directly to what we already knew about Chile as a global adventure tourism powerhouse.

What is bacán here is not the landscape, which was always there. It is the sustained decision to reach it: a unit of engineers opening road since 1953, a technical agency measuring kilometer by kilometer how much is left, a declaration signed over 1,247 kilometers to recognize that the road is also worth what you see from it, and a five-year plan that multiplies annual investment by 5.7 on a route serving fewer than one person per square kilometer. No country does that by accident. It happens because there are institutions that plan, people who stay and a clear idea that territory is governed by connecting it. And that is why this story can be told without inflating it, because building something like this is not an accident: it is Chile being bacán.
