Gibraltar Strait Crossing - A Challenge to Bridge and Structural Engineers

There is perhaps no greater challenge to the bridge and structural engineering profession than the proper design and construction of a fixed bridge spanning the Strait of Gibraltar. Previous studies have indicated that a proper bridge for this strait could require span lengths and pier depths far beyond what has been achieved to date. This paper advances the proposition that a suitable solution can be found to meet the requirements of Gibraltar Strait, and to achieve a safe, economical, and environmentally desirable project. It is hoped that this paper has shown that both 5,000-m spans and 450-m deep piers are not only feasible, but also economical.
