Main South closed between Coota and Harden

It doesn't rain, but.......

The Main south managed to get through the recent rain and floods relatively unscathed with only minor disruptions, but is now closed between Cootamundra and Harden following the failure of the Burley Griffin Way road overbridge at Wallendbeen.

Full possession of both up and down lines until midnight Wednesday 31/3 while they go about demolishing the bridge.

Does anyone know any history of this bridge? A quick look at Google Maps Street View from Silo Road appears to show brick sides, underpinned by steel work.

The bridge would date from the duplication of the line, which included the deviation between Jindalee and Wallendbeen via Morrison's Hill. This opened 17 June 1917, so the bridge would be about 103 years old. The brick walls were altered to provide wire mesh panels to allow visibilty of approaching vehicles on two roads just west of the line and one east of the line.

My information is that the brick abutments have subsided and the deck now fouls the loading gauge.

Since the road (Burley Griffin Way) is presumably closed at the bridge, vehicles may be diverted down the rather obviously named "Silo Road" west of the line that connects to the Olympic Way just west of the rail bridge on that road (to Young). Smaller vehicles could use an underpass south of the silos and drive through the town itself but trucks are unlikely to fit the underpass.

The existence of a reasonable bypass presumably reduces the need to replace the bridge quickly.

I note that ST24 XPT reversed at Cootamundra today, forming ST23.
Presumably buses were used from Sydney.

Ive travelled over this bridge countless times and its always been a rough one with the approaches needing patches on a regular basis.  Daresay it has been on the RMS watch list for sometime.  Hopefully they have a replacement plan ready to go with dual stack in mind so it doesnt need to be done for 100 more years.

Everything is being diverted via Cootamundra/Colac (or Jugiong for small vehicles) or Young/Boorowa - the local detours are not sufficient for the traffic of a B road.  Local traffic only from the Stockinbingal side, though the Olympic way of course is fine so its not hard to get to from the eastern side.

Does it take a lot of truck traffic?

I would expect the RMS or Transport NSW are frantically trying to find an interim fix to replace the failed bridge. Burley Griffin Way is a heavy haulage interstate route. B-doubles are having to travel via Cootamundra and Junee to get between Wallendbeen and Temora. BGWay is closed for the full length  between Wallendbeen and Temora at present.

I specifically asked about this at an ARTC presentation:

No double stack operation will be considered on the Main South north of Illabo.

Despite the fact that Illabo is half way to Sydney, double stack operation will be confined to the Inland Rail Corridor...

I assume you mean Coolac rather than Colac. which is between Warrnambool and Melbourne. I note that there appears to be a Colac Rest area on the Hume Highway near Coolac, but that's just confusing....

But sending people to the Hume Highway rather than letting them turn north at Cootamundra on the Olympic way, which they would have reached at Wallendbeen anyway seems strange (unless they were going to turn south at Wallendbeen).

A brick jack-arch bridge, NSW has many of them.

They consist of transverse broad flange beams placed side by side about 600mm apart, across between abutments and trestles.
A brick arch was built to fill in between beams, with rubble/aggregate fill between the top of the arches and the road.
The archilles heel of these bridges, and the cause of most of the failures, is corrosion of the beams. The web and top flange of the beam is hidden by the brick arch and rubble preventing the whole beam being exposed to the steely gaze of the Bridge Examiner.

Google Maps Street View shows remediation work has been conducted on/around the Dn side abutment (can't see the Up side), so there may be a history of problems here.

Quite a bit.  Its the main truck run from the Riverina to Sydney, and theres lots of grain going to the coast too.

Yes,

Some grain trains from Cootamundra to Port Kembla have run via Stockinbingal and Parkes.
Today's NY3 Newcastle- Whyalla steel train has run via the mountains.

So yes...

Photos have been posted on Facebook.

This is an open site and can be viewed without group membership.

The eastern abutment next to the down line has slipped downward by about a metre.
The embankment around this abutment had previously been reinforced using sprayed concrete to reduce erosion.

The concrete has cracked and moved with the subsiding embankment.

This isn't going to be fixed quickly.

I have frequently photographed trains from and adjacent to this bridge.
It moved noticeably even with cars crossing.
It was too narrow to stand on the bridge as a truck crossed but it didn't sound good.

Edit: The facebook post linked above has disappeared.... It was the only photo of the failed bridge I've seen.

A grain train with 3 x 82's was put away in the up relief at Katoomba for a while and although I don't recall the train number it was not a usual western line number. Maybe a diverted grain.

Sadly, that isn't the bridge that failed!

That bridge at the station leads to town, and is on George Street. But it probably is the same age or older..

The bridge that failed is out of sight in the distance in that photo.

The failed bridge is on Burley Griffin Way, about a kilometre south of town.
The failed bridge has had most of the brick walls replaced by chain wire fences for visibility.

Scomo is likes to rant about shovel ready projects to boost the economy. Here is an opportunity.

RMS should do following:
1) Short term fix - widen Silo Rd between Olympic Hwy and Burley Griffen Way to a proper 2 lane width. Trucks can use this approx 3km detour.
2) Long term fix - build new road bridge. In perfect world it would be gold plated - built for double stacked containers. But bridge at existing height is what would happen.

I'm told that demolition of the existing bridge is going ahead and that it is pretty much down to the steelwork now.

That should be completed this week.

The junction between Silo Road and the Olympic Way is unsuitable for large trucks and the visibility is poor.
It is probably better for all road traffic to go via Stockingbingal to Cootamundra West until the new bridge is complete.

The main problem will be building a secure abutment on the eastern side, which will probably have to extend down to track level to avoid the existing problem of subsidence and construction of this might affect rail traffic.

Maybe someone, somewhere knows, but it only happened four days ago.

Lots of stakeholders involved, and pretty sure it's not the track owners responsibility.

It was a "railway's" bridge so would be ARTC's problem now, unless there's a get out clause in their contract. However, I'm sure that RMS is a more than interested bystander.

Bridge ownership tends be by who needs/wants it built. The road would have pre-existed the railway. The current bridge may have replaced a single track structure, or maybe even a level crossing.
