Replacement of the Cameron Street bridge in Prince George, BC, involved demolition of the existing timber Howe truss bridge superstructure, reconstruction of the existing pier caps, construction of new abutments and installation of a new 4 span, 187 m long, steel girder, two lane bridge.
IDL Projects Inc. (IDL) engaged Allnorth to provide construction engineering services for the project. These services included conceptual and detailed designs, liaison with the bridge designers, plus construction inspections and supervision. An innovative approach was developed for the demolition and launch procedure by utilizing the existing timber bridge to launch the new superstructure. During the launch, each span of the existing truss was “picked-up” and dismantled piece by piece to meet the contract salvage requirements.
