The Code applies to the design, evaluation, and structural rehabilitation design of fixed and movable highway bridges in Canada. CSA S6-00, There is no limit on span length, but the provisions do not necessarily cover all aspects of design for every type of long span bridge. Provisions are also included for the design of pedestrian bridges, retaining walls, barriers, and highway accessory supports of a structural nature, such as lighting poles and sign support structures.
The Code is not intended to apply to public utility structures nor to bridges used solely for railway or rail transit purposes.
Requirements are not specified for the consideration of coastal effects such as exposure to sea action and icebergs, nor for conditions in high mountain terrain such as avalanche effects. Experienced specialists must be retained to advise on or review the design of structures that may be subject to such effects, and must ensure that all relevant and applicable requirements of other codes are met.
For bridges not entirely within the scope of the Code, its provisions apply only when appropriate. All necessary additional or alternative design criteria are subject to Approval. Several Sections have Appendices that contain less frequently used or referenced material. These Appendices should be considered as part of the Section to which they are appended, CSA S6-00.
