DESIGN OF THE PUENTE CHACAO PROJECT Alvaro F. Alrruiz Fajuri Inspector Fiscal Puente Chacao https://www.youtube.com/watch?v=qxNJVE9jwOY INTRODUCTION Because of its location, communications with the Isla Grande de Chiloe (Chiloe Island), located at the northern end of the Chilean archipelago of Chiloe, have been problematic since early Spanish settlement in the 16th century. The natural beauty and unique cultural heritage, represented by the UNECSO World Heritage designation for many of the island's wooden churches, have made Chiloe a destination for national and international tourism. However, the island's connectivity issues have long presented challenges for economic development and access to many essential services. A ferry system across the Chacao Channel between the communities of Chacao and Pargua is the primary access to the mainland for nearly all of the island's approximately 150,000 residents. Crossing times of 45 minutes or more are not uncommon, with long delays frequently resulting from weather, sea conditions, and seasonal traffic demands. In recognition of the local and national benefits of a more rapid and reliable connection, the Chilean Government committed to construction of a fixed crossing to Chiloe. When completed, the Chacao Bridge (Puente Chacao) project will provide residents and tourists with an all-weather connection to Route 5, the major north-south national trunk highway, as well as Puerto Montt, the largest regional population center. 1/2019
