I am not there till Dec, so cant say if the overhead arr road from Joyce Dr up to T2/T3 dep has completed, googlemaps does not give any updates, ...
Some show the pylons, and some show still the lorries and tractors.
Will do the Sarah St hotel stay, and then get the 350 bus stop thats behind it to get around.
$18.70 capped is still quite a high sum to meet, for max day fare, compared to $11 for MEL, and same for ADL.

Not forgetting that now, all traffic comes down past the Stamford, all in one direction, and going up the other way, is via 7th Ave.
They changed the traffic flow, the first time I used the 350 after the changes, (I didnt know), thought the bus driver had missed a turnff!
Going up via Robey St nowadays, and coming down via ORiordan.
