The Aluna Channel Bridge-Tunnel, officially the Aluna Channel Bridge-Tunnel and Causeway System, is a 59.4 kilometres (36.9 mi) crossing over the Aluna Channel between the Cartadanian states of Alexandria and São Ricardo. Connecting the city of New Venceia and Ricardo County, it forms the western portion of the larger Fortuna Expressway and more largely, IH-90.
Completed in 2014, the SCBT is the second-most expensive individual federal highway project in the country, preceded only by the Marée Channel Bridge-Tunnel, which adjoins the Fortuna Expressway and connects São Ricardo to Milan.
