The Department for Planning and Infrastructure has provided the following update in respect to the Principal Shared Path in Baldvis (end of Kwianna Freeway).
Southern Gateway Alliance (SGA) will temporarily close the Principal Shared Path (PSP) at the end of the Kwinana Freeway in Baldivis to allow for the construction of the Safety Bay Road interchange, as part of the New Perth Bunbury Highway (NPBH) project.
The north and southbound traffic lanes at the end of the Kwinana Freeway in Baldivis will be temporarily diverted to the west to allow for the construction of the Safety Bay Road interchange as part of the New Perth Bunbury Highway.
Subsequently, the temporary lanes will encroach onto the PSP and in order to ensure the safety of cyclists and pedestrians the path will be temporarily closed and users will be detoured around the work site.
