The Bayfield River Bridge is the fourth accelerated bridge construction project to be completed using the GiGo Bridge model and the first to be completed under staged construction, while the others were all complete under full road closure. One lane, two-way traffic was maintained at all times due to a long detour route alternative. The preliminary design called for the replacement to use conventional construction techniques and was scheduled to occur over 2 to 3 years. Based on the recent success of previous two GiGo Bridge projects, the concept was determined to be a feasible alternative which would reduce construction to a single season with a duration of approximately 8 months. The new 40 m single-span integral abutment bridge consists of precast abutments and wingwalls and four (4) “supermodules”. The supermodules consist of a steel box girder with a reinforced cast-in-place concrete deck, each weighing approximately 100 tonnes.
