The University of Sydney School of Civil Engineering CIVIL 3811/9811 – Tutorial Solutions – Week 6 In September 2003 the RTA invited proposals to form an Alliance to build the two connecting bridges on Lawrence Hargrave Drive to solve the rock fall problems experienced there since time immemorial. Part One of this oral history project dealt with the background of the communities that live along Lawrence Hargrave Drive, the geography and the geology of the area, and the process of forming the Alliance. A combination of box girder concrete in situ balanced cantilevers and box girders incrementally launched were used during the construction of the sea cliff bridge. Bridgework underway – balanced cantilever (top of photo) and incrementally launched (bottom) Southern balanced cantilever bridgework Commencement of balanced cantilever bridge spans Balanced cantilever bridge spans approaching Balanced cantilever bridge spans about to meet Overhead view of northern incrementally launched bridge Northern incrementally launched bridge However, in the Melbourne City Link Bolte Bridge (four-span, the balanced cantilever cast-in-place box girder bridge was considered as the construction technique) References 1) Oral History Program, Building bridges, LAWRENCE HARGRAVE DRIVE (PART 2), Summary Report, RTA, June 2006
