Weight limit, Waianiwa rail overbridge

A structural assessment of the Waianiwa rail overbridge on Argyle Otahuti Road indicates the structure is nearing the end of its life.

To prolong the life of the bridge until it can be replaced, Southland District Council is posting a 3,500kg weight limit on it, which means it can be used by light vehicles only.

Private vehicles up to the size of a ute and trailer will still be able to cross the bridge safely. Signage advising of the posting will be installed.

A detour for heavier vehicles is available via Waianiwa Oporo Road, Oporo Flat Road and Lincoln Road.

We expect these restrictions to remain in place until a new bridge can be constructed. Although the overbridge was not previously posted it was earmarked for replacement within the next 10 years. We anticipate bringing the replacement forward and completing this work within the next 24 months.
