Dundas Street Crossing of Sixteen Mile Creek: A Field Spliced, Post-Tensioned Precast Concrete Girder Bridge

Precast concrete girders are often chosen for short and medium span crossings because of their excellent economy. For most bridges, girder lengths are typically governed by local transportation restrictions; however, increased span lengths facilitated by field spliced girders reduce the number of piers required, which in some applications will eliminate in-water work. At the Dundas Street crossing of Sixteen Mile Creek in Oakville, Ontario, innovative use of a custom gantry system facilitated placement of 61 metre long, field spliced, post-tensioned precast concrete girders. The three 61 metre main spans consisted of three individual pre-cast prestressed concrete girder segments. These segments were joined together on-site using cast-in-place field splices and post tensioning cables in splicing beds located behind each abutment. The splicing beds facilitated seven girders simultaneously, corresponding to each of the girder lines within the new bridge. Using a gantry system, all seven girders in each span were sequentially lifted and longitudinally launched within a single day. After placing all of the girders and casting the diaphragms, the multi-span continuous 276 metre long girders were post-tensioned. This paper presents a design narrative for this field spliced, post-tensioned precast concrete girder bridge followed by a description of the construction process with special emphases on girder erection and temporary works.
