The Project consists of the replacement of the Highway 3 Grand River Bridge located just west of Cayuga, Ontario. The existing bridge is a five span steel truss with concrete deck, piers and abutments.
The project scope involves;
- Construction of a dock along the shores of The Grand River for barge access.
- Installation of independent temporary piers and foundations adjacent to the existing bridge. Installation of the foundation and substructure to occur off of the barges.
- Installation of girders. The girders will be installed from a barge by a crane.
- Form and pour cast in place deck.
- Installation of temporary retaining wall and shoring to allow for construction of detour approaches.
- Detour traffic from the existing structure to the new structure.
- Removal of deck on the existing structure at the piers.
- Installation of work platform around the existing piers to allow for pier cap widening.
- Sawcut existing deck and remove concrete by lowering the deck sections onto barges located below.
- Removal of existing truss spans. Truss spans to be cut apart and lowered onto barges located below.
- Utilization of the new bridge as a work platform to rehabilitate and widen the existing piers.
- Installation of a temporary skid-way for the temporary foundation to the existing rehabilitated and widened piers. Jack up the new bridge and install rollers.
- Jack the entire bridge to the north into the existing alignment.
- Installation of the expansion joints and asphalt pavement of final approaches.
- Removal of existing detour and temporary foundation from the barge.
Construction commenced in late 2012 with an anticipated completion date of 2015.
