TRAFFIC on Mandurah Road between Fifty Road and Tincombe Grove will be redirected until about May 19 as the Safety Bay Road roundabout is upgraded.
The upgrade, which began yesterday, will accommodate for two lanes of traffic upon completion.
City of Rockingham has urged motorists to seek alternate southbound routes, such as Ennis Avenue or Baldivis Road.
Northbound traffic on Mandurah Road through the worksite will not be affected, however motorists should approach with caution and observe traffic management directions.
The works will be undertaken in two parts with the approach lanes north of the roundabout constructed first followed by the construction of the exit lanes south of the roundabout.
Construction of the approach lanes north of the roundabout will take approximately three weeks to complete.
The southbound lane of Mandurah Road between Fifty Road and Safety Bay Road will be closed to traffic during this time and a detour will be in place along Fifty Road/Eighty Road/Safety Bay Road.
Once these works are complete, the southbound lane will be re-opened to traffic under appropriate traffic management and construction of the exit lanes south of the roundabout will commence with an estimated completion date of May 2.
The works have been scheduled during the school holidays to reduce the impact on Baldivis Primary School due to the additional traffic expected on Fifty Road.
The scheduling of the road closures also take into consideration other works currently underway on Safety Bay Road between Eighty Road and Nairn Drive.
