Transport Infrastructures

Ranging from major construction projects to the rehabilitation of pedestrian, road and rail bridges to overpasses, automated people mover and underground transit systems, ADF Group has developed extensive expertise in this field, both at the connection engineering level and fabrication processes and handling methods in the plant and installation of heavy steel components and complex steel structures. In fact, the environment in which these steel structures are erected is more demanding due to road restrictions, urban constraints or the location of the sites.


Dematteo Construction, Boston


Cambridge Seven Associates


Weidlinger Associates

This project, which was part of the Logan airport expansion in Boston, required the fabrication and installation of over 2 000 tons of structural steel of pedestrian bridges linking different buildings of the airport.

The bridge sections, because of their size and complexity, had to be pre-assembled in ADF’s plant in Quebec and shipped by barge to the airport in Boston, Massachusetts, a trip of approximately 800 miles (1 200 km).
