The
media release says they're doing pavement upgrades and comprehensive investigations for unspecified upgrades of the two intersections at Table Top. It's reminiscent of the Coopernook intersections on the Pacific Hwy but without an obvious conversion to an interchange. It looks to me like the other intersections south of the Olympic Hwy could be taken care of by new access which would for the most part fit within the road reserve.
I had a look on GSV and found that there were many signs peeling after only twenty or so years and in 2024 some were replaced, with borderless M31s of course. The only one of this cohort with the Hume actually named was the eastbound AD on Thurgoona Dr which does have "MWY". There are also several on the Riverina Hwy which were in need of replacement but the most recent image is only 2023, so they might have been done too. I noticed a few surprisingly bad sign placements at that interchange. The c. 2021 signs for the Davey Rd south-facing ramps use "HIGHWAY"
Here's the unusual exit sign for the Riverina Hwy. There's a notch in the fence to fit its conventionally-designed predecessor. I also found
this facepalm that was mentioned in a much older conversation on here, but while thankfully it's gone, for some reason they've put "To" in front of the borderless M31 even though it's an ordinary on ramp. There's also
this exit AD for the new Davey Rd northbound offramp originally without any route number.
