With increases in urban density, high speed transport networks and the safe separation of transport modes, transport structures are now an essential and intrinsic component of transport infrastructures projects.
Design, construction and management of these structures require a sound appreciation of competing needs such as capital budgets, constructability, durability, service life and stakeholder objectives. Tonkin is experienced in planning, design, documentation, construction and asset management of a range of transport structures.
