yes, I encountered the surprise pathworks this morning - an excavator was digging up the path already. From the west there are a couple of detour signs at the Morphett & then Deeds rd pathway exits. It wouldn't have have hurt to stick a sign (just an A4 printout would do) warning of the upcoming work on a pole a week or two ago.
Path was open again this morning.
Noted thanks, I'm twice a week through there for an Outer Harbour loop but have been avoiding it, appreciate the update.
