In 1958, the original Burlington Bay Skyway, a 4 lane high level crossing for the Queen Elizabeth Way over the shipping canal to the Hamilton Harbour was opened. Due to increasing traffic volume and congestion over the last 25 years there was a need to increase the capacity of the crossing. The construction of a parallel bridge to double the traffic capacity began in 1983 and will be completed by te fall of 1985. The twinning was let in one contract of $38.8 million and represents the largest contract awarded by the Ontario Ministry of Transportation and Communications. One contract was required in order to take full advantage of alternative design concepts permitted at the tender stage. This method is in contrast to the many contracts used for the one design used for the original bridge. The main events and criteria leading up to the decision to design a new bridge are reviewed. This is the first large bridge, an overall length of 2215 m with a main span of 151 m and width of 21.25 m to be designed in accordance with the Ontario Highway Bridge Design Code. Two alternatie designs were prepared in a manner that allowed for four possible options to be bid. During the design process, a high priority was placed on ease of construction, repetitive use of standard components and long term durability. The paper reviews the selection of the structural forms used, the application of the design criteria and the special precautions taken to minimize future maintenance. The selection of the lowest tender resulted in the construction of structural steel box girder approach spans and cast-in-place segmental concrete box girder main spans. The contractor was able to shorten the proposed construction schedule by one year. The paper provides a brief review of construction and how the initial design decisions affected the construction phase. (Author)
