A weight and speed restriction is in place on Bridge 93 on St Bathans Loop Rd because of issues with erosion.

Following two recent flooding events, there has been some erosion of the clay layer around the bridge abutments.

As a result, a heavy vehicle restriction of 5 tonnes gross maximum, and a 30kmh speed limit has been placed on all vehicles crossing the bridge.

Central Otago District Council manager for infrastructure services Quinton Penniall said water levels were still high, which presented challenges in managing the erosion.

The council roading team was monitoring the bridge daily and more information would be available as water levels dropped and a full assessment could be undertaken.

‘‘We are aware that Saint Bathans Loop Rd is a key route, and therefore a high priority that needs attention in case there is another flood event,’’ Mr Penniall said.

The council would provide an update when possible.
