To safely facilitate these works, traffic will be reduced to a single lane with temporary traffic signals in place to control the direction of traffic. Speed restrictions will also be in place throughout the work area for the duration of the project.

Road users are asked to please plan ahead, expect delays, allow extra travel time and take extra care when workers are on site. Observe speed limits, lane restrictions and traffic controllers when travelling through the area.

Access for emergency service vehicles and public transport will be maintained at all times during the works.

Access to properties will be maintained throughout the works wherever possible, with advance notice provided if there is a need to temporarily restrict driveway access.

Pedestrians and cyclists are advised to take care when travelling through the area. For safety reasons there may be some restricted access. Where required, signage will be in place to direct pedestrians and cyclists to alternative routes. Every effort will be made to minimise impacts to the community.
