Chacao Channel bridge

The Chacao Channel Bridge, also known as the Chiloé Bicentennial Bridge, is a suspension bridge currently under construction to link Chiloé Island with mainland Chile across the Chacao Channel. First proposed in the 1960s and repeatedly delayed, revived, and cancelled over the following decades, the project was one of several intended to commemorate Chile's bicentennial in 2010. Construction of the current design began in 2017. When completed, it will be the largest suspension bridge in South America and Latin America. The opening of the bridge is planned for the second half of 2028.

The bridge will replace the ferry service that has long connected the village of Chacao on Chiloé Island with the village of Pargua on the mainland, and its construction has been the subject of decades of political and social debate over its cost, benefits, and environmental and cultural impact on the archipelago.
