From Medellín

An hour and a half

Before you reach Santa Fe de Antioquia, the road from Medellín cuts through the mountain in a tunnel more than 4 kilometers long. And a few kilometers from town, a 19th-century suspension bridge crosses the Cauca River between two brick towers. They are two engineering works from very different eras that changed the history of western Antioquia.

In this guide we tell you the history of the Puente de Occidente (Western Bridge) and the Túnel de Occidente (Western Tunnel), fun facts about each, and how to visit them.

The Puente de Occidente

The Puente de Occidente crosses the Cauca River and links the municipalities of Santa Fe de Antioquia and Olaya. It was designed by Antioquian engineer José María Villa and built between 1887 and 1895. At 291 meters long, it was one of the longest suspension bridges in the Americas in its day.

Its structure combines materials of different origins: brick and stone towers, steel cables and a wooden deck you walk on. It was built at a time when the region had little more than mule trails, which made its construction a true feat.

Why it matters

In the 19th century, crossing the Cauca River was a challenge: it had to be done by canoe or raft, at risk to people, animals and goods. The bridge connected Medellín with western Antioquia and with the route to the sea, and made trade in the region easier for decades.

Today it’s a symbol of Colombian engineering. It was declared a National Monument by Law 25 of 1978 and is on Colombia’s UNESCO Tentative List to be considered a World Heritage Site.

José María Villa, the engineer

José María Villa was born in Sopetrán, a nearby town, and studied engineering in the United States. After returning to Antioquia he worked on other engineering projects in the region, but the Puente de Occidente is his best-known work.

Current status of the bridge

Because its structure had deteriorated, the bridge closed in March 2023 for restoration work. In July 2024 it reopened to pedestrians and light vehicles, with weight limits and limits on how many people can be on it at the same time, to protect the structure.

The Túnel de Occidente

The Túnel de Occidente Fernando Gómez Martínez runs through the Cordillera Central (Central Andes range) between Medellín and San Jerónimo. It is about 4.6 kilometers long and opened around 2006. Before, the trip to Santa Fe de Antioquia climbed over the mountain on winding roads and took considerably longer; with the tunnel, the journey takes about an hour and a half.

On August 4, 2022, a parallel second tunnel went into operation, part of the Vía al Mar (road to the sea) works. It separates the two directions of traffic and makes the trip safer and smoother.

When you come out of the tunnel the landscape changes completely: the green mountains of the Aburrá Valley give way to a dry, hot canyon, with small-leaved trees, cacti and the Cauca River below. It’s a good sign that you’re reaching tierra caliente (hot country).

The tunnel is the gateway to a warm-weather region, with towns such as San Jerónimo, Sopetrán and Santa Fe de Antioquia, which paisas (people from Antioquia) visit a lot to relax on weekends.

How to visit them

• On a tour: the Santa Fe de Antioquia Tour goes through the Túnel de Occidente and includes a visit to the Puente de Occidente, the historic center and the Juan del Corral Museum, with breakfast and lunch.
• On your own: the bridge is about 5 kilometers from the main square of Santa Fe de Antioquia. You can get there by car or local transportation, and cross it on foot.
• Best time: early in the morning or late in the afternoon, when the sun is less intense and the light is better for photos.

Fun facts

• When it opened, the Puente de Occidente was one of the longest suspension bridges on the continent.
• It has been restored several times over its history to preserve its original structure.
• The Túnel de Occidente is named after Fernando Gómez Martínez, a journalist and politician from Antioquia.
• Between the tunnel and the bridge, the landscape shifts from Medellín’s mild climate to the tropical dry forest of the Cauca canyon.
