The installation of the new floating jetty is underway at Greys Beach, North Nowra on the northern side of the Shoalhaven River.

The new construction will be a mirror image of the current floating jetty already in place at Greys Beach.

The new jetty includes four floating pontoons, six steel piles with HDPE (High-density polyethylene) sleeves and includes a variable floating access way.

The new structure will mean two floating jetties at the location.

Already the work is clearly visible, with a large crane used earlier in the week to insert six new pylons into the Shoalhaven River.

The pylons are imbedded many metres into the river bed and when the structure is complete it will have the capacity to withstand a one on 100 year flood.

The jetty also has the capability to be disengaged in the case of a flood and can be secured too or removed to higher ground.

Bell Rock Marine from Port Macquarie undertook the initial pylon installation work for major contractors Walcon Marine.

Installation of the pontoons and ramp is set to start next week with the facility's expected completion in November 2019.

The project is a partnership between the NSW State Government's Better Boating Program and Shoalhaven City Council.

The original wooden mini wharf structure located to the south of the new jetty will remain at the location.

The latest structure will mean three major jetty areas in the Shoalhaven River at Nowra with work on floating pontoons in front of the former Nowra Sailing Club site on the southern banks of the river, complete.

The floating pontoons are permanently secured to the bank by steel supports and steel gangway but can still be manouevered into a marina configuration.
