TBTE was retained by the Ministry of Transportation Ontario (MTO) for the replacement of a deteriorating restrictive underpass (CPR Subway) with a new structure highway and grade separated crossing bridge over the railway. The new highway and bridge structure would allow for the travel of oversize loads (bulk cargo) on this portion of the Trans Canada Highway, where previously there was a height restriction of less than 5 metres. Advanced engineering design and building materials to account for heavy traffic flow were project requirements, as was quickly and efficient construction of the new infrastructure (and demolition of the existing infrastructure) to minimise interruption to land and rail traffic. The solution involved realignment of 2.0 km of highway and a 26m prestressed concrete box girder bridge. The realigned highway included 3.75 metre main lanes, 2.5 metre fully paved shoulders, 1 metre rounding and rumble strips. As well, a 3.5 metre truck climbing lane and existing snow plow turnaround where reconstructed. Bridge components included piles set on rock points, RSS wall, prestressed concrete box girders, prestressed/precast concrete curbs, precast concrete approach slabs, metal railing system and GFRP reinforcing and UHPC with steel fibers for pre-cast connections.
