An Analysis of Long Spans of Fixed Link Crossings

This paper examines the long spans associated with fixed link crossings. An overview of existing fixed links globally, including information such as total lengths, maximum span lengths, materials and types of construction is given. Data for well-known major bridges such as the Oresund crossing as well as the more recent Çannakale Bridge are included. An overview of historical fixed link long spans will be given as well as a look to the future with an overview of some of those currently in design and construction stages. The use of prefabrication is investigated as a means of mitigating risk and increasing safety. The construction methods required to surmount the challenges associated with these long spans is examined. Finally, the paper looks at some of the long spans proposed for some of the more notable and long mooted fixed links.
