of Nigeria's civil war, a period of increasing oil price followed and Nigeria went through series of economic upturns. A need for improved infrastructural facilities especially in the capital city of Lagos that had gone through a period of port congestion and then an upward tick in vehicular traffic created the impetus for a third bridge linking the commercial-oriented Lagos Island with the growing urban settlements of mainland Lagos. A contract was awarded for a third mainland bridge in 1976. Construction of the bridge was done in phases. The first phase was contracted to a PGH consortium, a venture consisting, Impresit Girola and Borini Prono, while Trevi Group provided support services for piling. The first phase was designed to be 5 kilometers in length, starting from the Island and ending at Ebute Metta, towards Yaba. The bridge elevates to 3 kilometers above the water and made from pre-stressed reinforced concrete. Foundation piles had varying depths of between 36 and 54 meters and pile diameter is based on potential carrying road, diameters of 1500mm are used for the main bridge crossing the Lagos lagoon and for the slipway and approach roads, pile diameter was between 800mm and 1200mm. The first phase was completed in 1980. The second phase from Ebute-Metta to Oworonshoki was awarded to Julius Berger in Nigeria.
