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.
