Riding home from Ride of Silence, I saw the following sign:
Improving out Shared Paths
H A Smith Reserve
The City of Boroondara would like to inform you of the intended refurbishment of a section of the shared path between Glenferrie Road and the Velodrome.
Alternative access during construction is available along Reserve Road.
The map on the sign didn't work well in ASCII art :-)
However it shows work on the section of path between the street on the city side of the velodrome and the velodrome itself. That is, next to the HV tower where they are building the mobile phone base station. Coming from the east, you will be diverted off the path just before the velodrome, head north between the velodrome and the hockey field, then follow one road north then another road west before rejoining the path just west of the velodrome.
