Otara Bridge closed to heavy vehicles

On Friday 27 January 2023, it was brought to our attention that there was damage to Otara Bridge, which is located approximately 3km north of Ohingaiti to the east of State Highway 1.

An engineering consultant was immediately engaged to inspect the bridge and initial investigations determined that a compression failure had occurred to a main structural component of the bridge. As a result, the precautionary measure of reducing the allowable weight crossing the bridge to 6000kg gross was made and the speed limit has also been reduced to 10km/hr.

Various industry organisations, including the Road Transport Association and some local transport companies were contacted and advised of the restrictions to Otara Bridge.

At this time, the review of the existing structure and construction records has been completed. Bridge survey, hanger testing and interpretation and design of replacement truss is expected to be completed by the end of May 23.

The results of the investigations will identify the severity of the damage and will help determine the length of time the restrictions will remain in place. It will also provide us a basis for the repairs required and the likely cost.

Variable Message Signage (VMS) boards installed on SH1, advising of the reduction of weight limits on Otara Bridge and signage installed on Otara Road advising of the reduction of weight and speed will remain in place for the duration.

We will update the situation as it progresses.
