Moose Creek Bridge – Case Study of a Prefabricated Integral Abutment Bridge in Canada

This paper describes the design and construction issues of a single span prefabricated integral abutment bridge. The superstructure consists of precast prestressed girder/full depth deck elements and the substructure consists of precast abutment stem and wingwall units. The units were fabricated at the precast plant and transported to the site where they were assembled using closure strips. Integral abutment bridges are the most common type of bridges now used in Ontario. Moose Creek Bridge is the first integral abutment type bridge built in Ontario using the T-shaped prefabricated girder deck system. The abutments were made monolithic with the deck by casting concrete closure segments. Use of prefabricated bridge systems to construct bridges reduces construction time considerably and enhances the quality due to fabrication in a controlled environment. Prefabricated bridge systems also provide a number of other significant advantages such as reduced traffic impact, improved construction zone safety and less disruption to the environment. The Ontario Ministry of Transportation investigated the suitability of the T-shaped girders with closure concrete pours to connect the T-beams. Scaled models of the system were tested in the Ministry’s research lab and were found to behave adequately under static and cyclic load tests. It was decided to test the concept by constructing a prototype bridge and to evaluate construction issues and performance under site conditions. Moose Creek Bridge was selected due to its size, simplicity and construction schedule.
