Shellharbour City Council says more than $1.1 million of the $2.9 million works to be funded by a 9.3 per cent rate rise this financial year has been completed.
The council has resurfaced 18 roads at a cost of $1,068,000 including Benson and College avenues in the city centre, Russell Street in Albion Park, Captain Cook Drive in Barrack Heights and King Street in Warilla.
Construction of the new amenities block at Reddall Reserve will begin this month.
The building will provide a unisex accessible toilet, male and female change rooms and two male and female toilets.
The total cost is $275,000 and demolition of the existing building will begin next month.
"Upgrade of these amenities will be welcomed by users of this facility and surrounding beach, lake and foreshore area," Shellharbour Mayor Marianne Saliba said.
Work has also started on the refurbishment of Yovelton House in Albion Park Rail.
Two picnic shelters in Boonerah Point Reserve, Mount Warrigal are due for completion next month.
"The itinerary of works has been scheduled with priority given to roads, footpaths, buildings or pipes that impact the greatest number of people and has any potential safety issue," she said.
