A second barge has arrived in Batemans Bay as part of the construction of the new Batemans Bay Bridge.
It arrived in the area on Tuesday, August 13, and will be anchored upstream of the Batemans Bay Bridge within an exclusion zone marked by yellow buoys.
A lift opening is scheduled sometime between 1.15pm and 1.45pm on Wednesday, August 14, and is expected to take approximately 20 minutes.
An RMS spokesperson said the lift is required at this time to make use of favourable tide and weather conditions, and may cause delays along the Princes and Kings highways.
"If conditions are not suitable for the lift, the community will be notified of a new date and time," they said.
The barge left the Brisbane River on Tuesday, August 6, before mooring in Jervis Bay due to high winds and large sea swells.
The barge is about 21 metres wide and 55 metres long, and weighs about 2300 tonne.
It has been thoroughly cleaned before entering the Clyde River to protect the area from biohazardous materials.
All vessel operators in the area should exercise extreme caution around the barge.
