| Abstract: |
The construction of the new Metro of Oporto was one of the largest infrastructure projects developed in Portugal in the last decade. A light train system, with a large part at ground surface in addition to the underground network was shown to be the most technical and economically convenient option. A variety of bridge projects were developed for this new network, from new long viaducts, upgrade of an old masonry bridge and “last but not least” the railroad addition to the 19th century Luiz I bridge. The design of these bridges were developed by the authors in a turnkey design and built contract. The study of construction and erection schemes was included in the design, namely to insure stability during the retrofitting of Luiz I bridge keeping the roadway traffic in the lower deck. |
