Part of Kinghorne Street will be closed on both days to allow the next stage of construction of the $8.5 million Quest serviced apartments.

Joss Construction are undertaking the work on the four-storey block of 41 serviced apartments on the former Nowra Mazda car yard site on the corner of Kinghorne and Plunkett streets.

The southbound lane of Kinghorne Street between Worrigee and Plunkett streets will be closed to traffic between 5.30am and 3.30pm to allow a crane to lift the large prefabricated concrete walls into place.

The northbound lane of Kinghorne Street will remain open to traffic, but southbound motorists will have diversions around the area.
