A faster commute for the families of Temuco and Padre Las Casas

The Cautín River in Chile separates the communities of Temuco, capital of the Araucanía Region and economic hub, and the growing city of Padre Las Casas. Many families commute between the two cities for work in their cars, or by bus and taxi.

As the communities of Temuco and Padre Las Casas have grown, road infrastructure has not been able to keep pace with travel demand. The business districts of the city and the approaches to the two existing crossings over the Cautín River regularly experience high levels of traffic congestion, inadequate traffic signage and increasingly long commuting times between the two cities.

Louis Berger provided concept design, detail design and construction supervision for a third bridge connecting Temuco and Padre Las Casas. The bridge is part of a larger infrastructure development initiative that will substantially improve vehicular traffic between the two cities with 15 kilometers of new roads, two railway bridges, five roadway bridges, two urban parks and nine kilometers of cycle routes.

Beyond its promise to improve the quality of life for families who travel daily between Temuco and Padre Las Casas, the new bridge will also be a prominent local landmark. Also known as the Treng Treng & Kay Kay Bridge, the Temuco Bridge is designed as an asymmetric cable-stayed structure that symbolizes the Mapuche legend about the Earth’s formation. The two poles united at the top represent the universal struggle between good and evil.

The first stone of the Temuco Bridge was laid in May 2014.
