The upgrade works on Cooper and Charlton streets will begin with the installation of a new raised road pavement to improve pedestrian amenity.

As part of the works, planter boxes, street trees and bench seating will also be installed to enhance the streetscape. Drainage works will also form part of the project.

Cessnock Council's infrastructure manager Katrina Kerr said council was staging the works to limit disruption to the community and business owners in the CBD.

"Disruption to the community is unavoidable when the site is in the heart of the Cessnock CBD. Council is working to ensure measures are in place to limit disruption," she said.

"We have spoken with individual businesses directly impacted by the works and will continue to do so.

"The program of works has been designed with businesses in mind including some night works.

"Temporary pedestrian access will also be in place to ensure foot traffic can navigate the work site and access businesses throughout the construction period."

The works will take place in three stages to allow one way traffic access through the work zone. Traffic flows will return as normal between August and September.

"It's exciting to be undertaking works that will vastly improve the amenity of Cessnock for both locals and visitors," Cessnock mayor Bob Pynsent said.

"The works at Bridges Hill Park Playground and the associated access improvements are a vital component of this project.

"We can already see the benefits of these upgrades. We look forward to seeing the revitalisation now brought to life in the CBD.

"This is about creating a place for all to enjoy, that is safe and better connected."

The works are part of the Cessnock CBD Revitalisation Plan which includes the Bridges Hill Park Playground project and access improvement upgrades.
