In the last two decades a new fundamental road network was undertaken at Madeira Island. Due to the vigorous relief of the Island, the great heterogeneity, the structural and lithological complexity of volcanic rock formations and to the land occupation, tunnels became dominant and a large spectrum of innovative structural tunnel solutions were developed. The objective of this paper is to give a global vision of the importance of this group of infrastructures, focusing in the new fundamental road network evolution and construction of road tunnels at the island and in the conception and design aspects, along with the description of the geological-geotechnical conditions, primary and secondary lining, phased construction and monitoring.
