Yesterday and today the Sydney Harbour Bridge was closed to all
traffic except buses, taxis & motorbikes to allow for resurfacing of
the pavement. The same will occur the following two weekends, weather
permitting. Here are some shots I took yesterday:

Thanks for photos!
This means of completing the job appears to be fairly disruptive
(although I suppose the tunnel offers an alternate route without too
much inconvenience). Are you aware of why they are going about this
with a complete closure compared with the more usual practice of closing
down one or two lanes overnight?

Indeed, great photos!
Just a question: with the Bridge now fully electronically tolled, why aren't there any plans to remove the toll gates? They slow down traffic unnecessarily and unless they're heritage listed, they ought to be pulled down like the M4 toll gates!

Interesting that the original message was sent on Sunday but only arrived today.
Apparently there was considerable congestion in the tunnel and its
approaches - not helped by an accident or two there. Motorists were
advised to use other crossings further up the harbour.

Two of Lijman's messages got stuck in the moderation queue but strangely I (as one of the mods) didn't get an automated email from Google about it, which is what normally happens if there's posts to be approved, new member requests etc etc. I only noticed it by chance when I happened to log in earlier today and let them through. Shouldn't have any future problems with his posts :)

They can't do the process (even if batched) in an overnight shutdown -
they need to remove all the asphalt and re-apply the water-proofing
membrane, let it dry and re-asphalt. So they're doing three lanes per
weekend, plus spare.
Buses were running.

Oh they probably have heritage value. Especially the fold-up set.
So a new site needs to be found, then a plan to move them developed,
then a budget to do it etc...

Glad my posts finally got through!
Here's all the info you need to know about the work:
http://www.rta.nsw.gov.au/roadprojects/projects/shb_precinct/resurfacing/index.html,
plus http://www.rta.nsw.gov.au/newsevents/events/shb_resurfacing_2012.html
Last Saturday when I was there traffic on the Warringah Freeway
accessing the southbound harbour tunnel was banked back to about
Falcon Street.
I assume that they have to close the bridge for two or three entire
weekends because they are stripping the pavement right back to the
original concrete deck (for the first time since the bridge opened 80
years ago), applying waterproofing to it (which needs 4 hours to dry)
then laying down new asphalt. All this no doubt takes longer than
regular resurfacing.
I too thought that this would be a good opportunity to remove the toll
gates at the southern plaza (and resurface that area too), but AFAIK
that's not happening. Apparently the northern toll gates are heritage-
listed, so I don't know what can be done with them. I assume only the
actual bridge structure itself (main span & approaches) is being
resurfaced, with the roadway on "dry land" at both ends not being
done. After the job is completed we'll see exactly how much was done.
The final go ahead for the work was only given last Thursday after
receiving the weather forecast from the BOM, as apparently rain can
affect the waterproofing process. It started raining in Sydney late on
Saturday and continued throughout Sunday, but AFAIK it didn't delay or
affect the work.
I might get more shots this weekend, weather permitting. I think they
will only need the third weekend if inclement weather delays the work.
Glad you enjoy the pics!
Cheers, Lijman.

Oh I forgot - buses, taxis, hire cars and motorbikes were still
allowed to cross the bridge, in groups when there were no works
vehicles in the open traffic lanes. Trains were running across, the
footpath and cycleway were open, and I guess ferries were operating as
normal, so the two sides of the harbour were not cut off from each
other.

I think they are heritage listed, if I remember correctly from some
news report around the time when the cash tolls were removed.
I drove over the bridge today, and the resurfaced northbound lanes are
very nice and smooth. Last time I was on the bridge it was a huge
rumble strip.
You could probably put an entire bus interchange alongside a
redesigned 6 lane carriageway in the toll booth footprint. No more
Wynyard bus backups!

I heard that the southern approach is getting reconfigured and most of
the removable medians being reorganised/removed. I think the toll
booths might be going.

Anyone know if today's rain has upset the schedule? The rain was pretty
heavy at times and I suspect this would have severely stuffed up
waterproofing works and asphalt laying.

going on. I went away for a few hours and by the time I returned at
around 4:30pm the rain had gone and it had dried out sufficiently so
they were back at it. I just got back from the bridge in the last 45
minutes or so and the waterproofing on the southern approach (lanes
4-6) was drying, the main span (lanes 4-6) had its final asphalt
surface down and they were waterproofing the northern approach (lanes
4-6). On the main span they put down a bitumen seal (tar spray & blue
metal) before laying the asphalt. I never saw them waterproofing the
main span so I don't know if they actually did. Maybe I was simply
never there when they did. Whether or not they are behind schedule I
don't know.

The newspapers keep talking up the activities and how it'll be done this week.
I so wish they'd be delayed so that next weekend there would be extra trains + buses + clearways everywhere (traffic along major corridors that I used such as Metroad 3, Parramatta Road etc were very very smooth!)

Cahill Expressway above Circular Quay at about 6:20pm today when I
noticed private cars beginning to pass by heading towards the Domain
Tunnel which meant that the southbound lanes on the bridge had been
opened just a few minutes earlier. Whether the northbound lanes had
been opened at the same time I don't know, but when I got back onto
the bridge at 7:30pm all lanes were open. Took heaps of pics yesterday
& today plus two videos, which I will post on Skyscrapercity in the
next few days and then put the links on here.

These lanes, over the former tram lines, have always had a visibly different surface to the rest of the bridge and are technically part of the Cahill Expressway. Not sure if this has anything to do with it.

Maybe the trams were an open steel mesh like the trains on the other
side so the deck underneath may not be the same as the rest of the
road lanes.

Lanes 7 & 8 were constructed about 25 years after the other lanes so I doubt they are in such dire need of reconstruction?
Are you sure these lanes are 'technically part of the Cahill Expressway' though? I've heard that before but I haven't seen anything official that indicates that. The Schedule of Classified Roads, for example, does not mention these lanes in the description for MR592 (Cahill Expressway) and they are not excluded from the description of MR632 (Bradfield Highway).

By 'technically' I meant that they would have been constructed as motor vehicle lanes as part of the Cahill project. I agree with you that they'd not be officially part of the Cahill Expressway but rather part of the Bradfield Highway.

I'm not sure about the official road status, but it is signposted as
the Cahill Expressway on the northern approaches to the bridge and it
seems legal to change from lane 8 to lane 7 off-peak (a prohibition
sign states that cars aren't allowed to use the exit in peak periods)
and continue on to the York and Grosvenor exit or the Western
Distributor, so the lanes seem to be classed as separate from the
Bradfield Highway, not just to guide people onto the Cahill
Expressway. I'm just assuming this because the signs should say 'To
Cahill Expressway' rather than signed as the actual Cahill Expressway
if it was the Bradfield Highway up to the elevated Circular Quay
section of the Expressway.

this all raises the question -
why can't the main deck carriageways be joined? The "Cahill
Expressway" lanes are really wide by virtue of their intended use, so
if lane 7 could be joined to the main deck and the whole role
restriped, you'd probably get 7 x 3.1m lanes instead of 6 x 2.9m lanes
and a 3.7m lane plus median.
(I say as who considers the best long-term use of lanes 7 and 8 for
the inneviatbly-necessary additional rail crossing of the Harbour)

You would have to move the tolling points, because if that were to
happen today you would end up having people using the Bradfield
Highway lanes to get onto the bridge and lane 7 to get off the bridge
(Lane 7 vehicles would have been tagged at Milsons Point), avoiding
any tag readers.
If an additional rail crossing of the Harbour is to be built, the
current southbound Cahill lanes should be used for the railway, and a
second roadway deck should be added onto the bridge, with 5 lanes for
general traffic (2 Cahill lanes+3 WD/City Exit lanes) and one bus lane
on each deck.

It's signposted as the Cahill Expressway as you basically can't go anywhere other than the Cahill Expressway from those lanes (yes I'm aware of the off-peak allowance but it's not a move that is encouraged). It's a bit like saying that the middle carriageways of the Warringah Fwy are part of the Tunnel and Bridge as far north as Ernest Street because that's what the signs say...

Awesome pix.
I bet that deck of the bridge hasn't seen the light of day since the thing was built.
The adhesive they're using with the waterproofing looks a lot like contact adhesive :)

The resurfacing of the Sydney Harbour Bridge fourteen years ago was widely reported - including by the roads minister - to have been the first removal and replacement of the asphalt surface since the bridge was completed in 1932. That was completely false! A detailed article in the September 1964 issue of Main Roads (Vol 30.1 p2) explains both the technical and traffic control details along with photographs, and explicitly mentions that they went down to the concrete. The surface had deteriorated by 1960 but it wasn't until the necessary plant was imported from the USA and trialled elsewhere that it was carried out. Rather than cold milling like nowadays they had heater units to soften it and then graders to scrape it off. They removal and bottom layer placement were done at night and the wearing course was done on Sundays as they couldn't get it as smooth at night.
