Bridge manual (SP/M/022)

This Bridge manual sets out the criteria for the design and evaluation of bridges, culverts, stock underpasses and subways, the design of earthworks and retaining structures.

The manual is a companion document to the overarching Highway structures design guide which provides general and specific design criteria for all highway structures.

Bridge manual - index - 2nd edition

The 2nd edition of the Bridge manual has been superseded by the 3rd edition.

For existing highway projects, confirmation should be sought from the NZTA, or the relevant road controlling authority for non-state highway schemes, whether this manual shall be used or designs should still be undertaken in accordance with the 2nd edition of the Bridge manual. Generally, the 3rd edition of the Bridge manual should be used for all highway projects commencing detailed design after 1 June 2013.

The 2nd edition of the Bridge manual therefore remains here for reference purposes.
