The Town of Victoria Park has had ongoing flooding issues in the Causeway underpass for a number of years mainly during high tide periods. Frequent complaints have been received from pedestrians and cyclists.
This issue is mainly caused by river water bubbling up between the existing paving. While there are two sump pumps installed to try to deal with the water infiltration, during periods of high tide they cannot cope with the volume of water flooding into the underpass.
The Town has now finalised the design and awarded a contract to upgrade the underpass to prevent this ongoing issue.
In order to facilitate these necessary works, it is anticipated that the underpass will not be able to be accessible by pedestrians or cyclists between the 6 February 2017 and the end of April 2017.
A series of detour maps are provided for pedestrians but it directs them straight through the MRWA works at Craig St which may or may not have a viable route through for pedestrians or cyclists (no maps are available but Craig St is completely closed between Burswood Drive and GEH until mid-March). Even if the detour is passable the paths are not of suitable width for pedestrians and bi-directional cycling movements so expect to be stuck behind pedestrians for extended distances.
As all the intersections into Burswood are in various states of construction I do not know what the next viable route is until you get under the railway/to the GFF.
If you need to ride this way it might be worth scouting out a viable route before the closure and if you have the option you might want to skip the area altogether.
