To relieve traffic congestion in Havana and enable the city to free up new urban spaces, GTM proposed to build a tunnel that proved far less expensive than the bridge solution recommended by US competitors. The structure was 1,600 metres long and was completed using five pre-stressed concrete caissons, which were more resistant than the weighted metal caissons used in the United States. This was demonstrated when a tidal wave in early 1958 had virtually no impact on the project. On the strength of this success, GTM signed another similar contract with the Cuban city.
