Driving the R-264 Road: The Wooden Bridges of Nininco and Las Corrientes
Located in the Araucanía Region of southern Chile, the R-264 is a secondary gravel route known for its traditional timber engineering. The road is a key local corridor featuring some of the most spectacular bridges in the world built entirely of wood, requiring strict adherence to weight limits and vehicle dimensions.

How is the road R-264 and its wooden bridges?
The R-264 road is a 10.5 km (6.52 miles) unpaved track running west-east, connecting the R-260 and R-86 roads. The route's primary technical challenge is the crossing of several riverbeds via timber structures. The most significant is Puente Las Corrientes, a wooden bridge spanning 38.40 meters. Further along the route, the road crosses the Estero Nininco via the Puente Nininco, a shorter 6-meter wooden structure. Both bridges share a similar structural design based on longitudinal wooden beams supported by timber pylons.
What are the weight limits on the R-264 bridges?
For both Puente Nininco and Puente Las Corrientes, the maximum weight limit is strictly 15 tons. Exceeding this limit poses a high risk of structural failure, as the timber deck and supporting beams are designed for light-to-medium local transit. Heavy trucks or industrial machinery should avoid this route. The narrow width of the wooden decks means that only one vehicle can cross at a time, requiring drivers to verify that the bridge is clear before committing to the crossing.
What are the driving hazards on the R-264 wooden bridges?
The primary driving hazard on the R-264 is the reduced friction coefficient of the wooden planks, especially when wet or covered in mud from the surrounding gravel sections. The transition between the gravel road and the wooden bridge deck can be abrupt, requiring low speeds to avoid suspension damage. Furthermore, the lack of substantial lateral guardrails on these structures increases the risk during high-wind events or heavy rain, common in the Araucanía Region. Drivers must inspect the state of the wooden planks, as loose or rotting timber can compromise tire traction.
Is the R-264 road open during the rainy season?
While the R-264 is technically open year-round, the integrity of the wooden bridges is highly sensitive to the water levels of the Estero Nininco and surrounding streams. During the intense winter rains of southern Chile, the structural pylons can be affected by debris carried by the current. It is recommended to check local conditions before transit, as high-clearance vehicles are necessary to navigate the muddy approaches to the bridges. There are no emergency services along this 10.5 km stretch, making self-sufficiency and mechanical reliability essential for any driver.
