Update:
Bridge 93 is closed to all vehicles exceeding 5 tonne gross.

A weight and speed restriction is in place on Bridge 93 at St Bathans Loop Road because of issues with erosion.
Following the two recent flooding events, there has been some erosion of the clay layer around the bridge abutments.
As a result, a heavy vehicle restriction was placed on the bridge and a 30km/hr speed limit on all vehicles crossing the bridge.
CODC Manager for Infrastructure Services, Quinton Penniall said water levels were still high, which was presenting some challenges in managing the erosion level that is occurring.
The Central Otago District Council roading team is monitoring the bridge daily and more information will be available as water levels drop and a full assessment can be undertaken.
“We are aware that Saint Bathans Loop Road is a key route, and therefore a high priority that needs attention in case there is another flood event,” Mr Penniall said.
“We are looking at some temporary measures such as dropping large rocks upstream to divert the flow straight down the middle of the bridge away from the western abutment, which is causing the erosion problem.”
The Council will be providing an update when possible.
