The 11th edition of CSA S6 Canadian Highway Bridge Design Code applies to the design, evaluation and structural rehabilitation design of fixed & movable highway bridges and establishes safety & reliability levels that are consistent across all jurisdictions in Canada. CSA S6 makes it easier for consultants and the construction industry to respond to calls for proposals and supports the implementation of a national highway transportation system with agreed minimum standards and loadings for bridges on interprovincial highways. Some of the key changes to CSA S6 include Section 4 (Seismic Design) and Section 5 (Methods of Analysis).
