The approach lanes north of the roundabout were completed and re-opened to traffic on Wednesday.
However, the southbound lane of Mandurah Road between Safety Bay Road and Tincombe Grove is set to be closed to traffic this week and a signposted detour will be in place along Safety Bay Road, Eighty Road and Pike Road.
Following completion of the exit lanes south of the roundabout, these lanes will be re-opened to traffic under appropriate traffic management by about Friday, May 27.
When the works are completed later this month, the approach to and exit from Safety Bay Road roundabout will accommodate two lanes of traffic.
