- The Marlee and Duffs Bridges over Dingo Creek, north of Wingham were two timber truss bridges requiring considerably more maintenance and Council budget expenditure compared to the remainder of the bridge stock.
Greater Taree City Council managed the demolition of the old and construction of two new three span two lane concrete bridges, including associated approach road works, road pavement, drainage and ancillary works.
The program and cost estimates were developed during the options stage very early in the lifecycle of the project. The project has proven the benefit of good project management on cost, quality, safety and program.
Duffs Bridge was opened five months early in November 2012, and Marlee Bridge was opened in April 2013 at a total cost of
approx. $6.8M.
The new bridge is great, but gonna miss the old one. It had character.
a project on schedule and on budget? very impressive!
Watch here more
I was almost 8 minutes in before I realized "tempry truss" was not a new type of truss I had never heard of, but in fact simply the Australian pronunciation of "temporary"
Terrible, I know progress has to be made but the little regard put into the historical significance, no matter how small, is extremely overlooked. Especially with local support to save the bridge and set aside money for its renewals, which were superseded. Disgusting waste of preservation.
What an innovative video for an innovative bridge built by innovative crews in an innovative town over an innovative river
Stands out from most other time lapse videos because of the detailed commentary Thanks.
Agree. Commentary adds perspective, details, and context that photos/videos can't do alone. It's a mistake that many YT videographers make, all video, no sound.
Yes
I am very impressed with this video. It clearly explains the planning, the problems, the solutions and is very entertaining. Definitely one of the best ones I have seen.
10 days. Impressive!!
I bet people still moaned 😂
They would moan if it was only 10mins , it's human nature to complain about anything , even if it's for betterment of human travels
I wish my area could do that in 10 days. Took my area 8 years to replace a 3 yard bridge and a new traffic light with a dedicated right turn
I like the low profile flowing bridge, but for such a short bridge they put a lot of work in to this.
it is mind boggling that this all was done in only 10 days. what a monumental task! The flow charts must have been enormous with massive details.
Yes it was dear
Nice-but they are driving on the wrong side of the road!!!!!!!
My head hurts from all the details in this video!
No oroblem dear
6:30 - you've got a 4x4? I drive a 500t all-terrain crane
Great build. Thanks for sharing. Cheers from USA .
Cheers bro
Count how many times the narrator says "Innovative". #lockdowngames
Bet they’re glad to have new bridges with all the fires in Australia.
Money well spent there. And flood proof. But, I guess pedestrians won't be using it.
With one car per week pedestrians should be safe
nice bridge but who stuffed up the asphalt ? you can clearly see the drop off when you come onto the bridge at both ends.
Indeed, saw the car going up and down at the end. Or at 18:20.
That’s how all bridges are like on highways in America, they just can not make a flush approach from either end.
They should have used this as inspiration in my city, when they changed a railway bridge... It took almost 2 years.
Great video. I love the time lapse footage! Most time lapse footage goes too fast to see what's happening. great job on a video well done!
Awesome job from start to finish... good planning...

Portable weber BBQ in back of the white ute.
mans got to eat lol
Guess what happened with them tiny cow's patiently grazing in the background 🥩🍻
this was way better planned and executed than the way they do it here in New Jersey. here the idiots close the road for a year to replace a smaller bridge . who knows what the sped on the dammed things but im sure far too much!
Or pretty much anywhere else in the US lol
To go off at a complete tangent. All those cranes and heavy equipment are powered by DIESEL. And always will be. The idea that heavy equipment and vehicles like that, and on a remote site, too, could ever be "battery electric" is completely absurd. For several reasons.
Yeah everybody wants it done for half of what it would actually cost.
And twice as quick..
The "music" is so annoying I cannot finish watching. Ridiculous.
Very interesting video. the new bridges looks nice and innovativ construction techniques were used .
A few gallons of gasoline would have taken care of the demo.
that annoying music sure does suck
Very impressive scheduling and budgeting. Now to do the same with the Morpeth bridge?
Watch more here
8:00 god damn those are some big wrenches
Pretty cool. I am not a civil engineer thought this was fun to watch. Good job Greater Taree City.
То ли дело мост который Терешкова открывала. Ах ну да у них просто страны меньше. Обнулись
You Aussies like your bridges narrow ! Trucks will trade mirrors on those two bridges!!
Great project, planning and work! 👍😎
Beautiful, high quality bridges. Well done.
Hello from Victoria Australia, Thank you, who would have thought something so useful could look so beautiful.
Yes dear
And you didn't save any of that beautiful old timber....
Odd they didn't allow room for pedestrian crossing as well.
Mate, you are in Australia.....there are no pedestrians
Australians swim across river crossing, it keeps their beers cool.
there aren't any
@EpiDemic117 They had room at the side, so I guess they could be added at a later date.
You're driving on the wrong side of the road you donut ! hahahaha
Impressive job and video. Cheers from Canada. indeed.
excellent video. Thanks. Good on ya mates.
до крымского моста Австралии далеко
Expertise in civil engineering here!
I like the cow wondering down the road at the end.
Curious that all of the Allan Truss bridges in the Maitland LGA are protected by Heritage listing, and maintained by the NSW Government. The Hinton bridge in particular looks like it is very similar to these two - the Morpeth and Dunmore bridges have significant differences. I take it that Taree Council were unable to secure that listing and get NSW funding to maintain them? Pity.
nobody searched for this video
Horrid music. Why does a time lapse with commentary need F'ing music? Thumbs down, had to stop watching because of the bass. Putting on the Do not recommend list.
Bla bla bla... can i just watch timelapse video without comments?
Asked you mother to turn of the sound?
In the US they would have blown up the old one making a huge mess. The environmental considerations of this project are very impressive.
The load-bearing beams, not exposed to time, still showed their solidity or do I see wrong?
I want to hope that they have been reused for non-load-bearing uses; such as sawn for cladding and the like.
They are part of your history
there is no 'E' in Asphalt... *facepalms*
Обама верни наши пенсии!!!))))))
Вася, ты забыл написать номер счета, куда перечислять. Налом не получается.
A lot of progressive language here.
that would take the 2 years and millions here in the UK, not to mention the cost to local business, and all the government would say is " yeah, sorry about that ", awesome film dude, you got my sub.
The concerns about the durability of transversal bars is something that we had a major issue with in Montreal. The Champlain bridge was one of the first few in the world to use that construction method. The use of those transversal means that should any of the elements of the bridge fail, you can't replace it. This resulted in the entire bridge having to be replaced at a cost of several billions. Given that this is a much smaller bridge, it likely isn't as much of an issue, but it's definitely something to keep in mind.
Probably not billions as you said, but certainly could be quite expensive - how long are the spans on the Champlain bridge compared to this one? Replacing a span on Champlain would probably cost at least what these two bridges cost combined, but I'm just taking a wild guess.
@@MikeT-TheRetiredColonel The Champlain bridge is a 3440 meter bridge. It's a major bridge, one of the most used in the whole of Canada. Even at such a massive cost, the economic damages of a bridge closure far outweigh any building costs. There's several hundred of millions dollars of freight being transported on it each year. It met an early demise because it's design meant that the deck and girders were one single unit which made it impossible to replace, or properly repair parts that failed. Several hundred millions were spent to extend it's life just a few more years until it's replacement was ready.
After just a few decades, they started to notice that there was premature wear and tear. They ended up using external reinforcements to strengthen the girders supporting the road deck. That caused additional stress in the pillar heads and they also had to reinforce those. Being such an important bridge, closure would only be considered as a last resort. Plans were put in place for a worse case senario, including the purchase of a massive steel girder that they refered to as "Super Poutre" beam that could quickly be installed on top of the road deck if necessary. The bridge was wired with several hundred sensors and was monitored 24/7. In addition, regular inspections were carried out. During one of those inspections, they found a hole in one of the concrete girders that was more then a meter. Just about all of the pre-stressed cables in that girder had failed and for all intents and purposes, it's load was now being carried by the remaining girders. Super poutre was installed and stayed there for months to keep traffic moving while emergency repairs were carried out.
The crazy thing is that while all of that was going on, government were still busy playing political games, delaying the replacement of what was now quite obviously a dangerous bridge. We had a highway viaduct collapse in the previous decade and the memories were still quite fresh. I think that Super poutre and the media attention that got is what finally did it and made the situation politically untenable. Once they finally start construction, it went up quick. Building a bridge on that scale is usually a process of a decade. They started in 2015 and finished it in 2019. Building started before the design was finalized. The new bridge is massive by any kind of scale, has a steel superstructure that can be repaired easily, or even partially replaced as needed. The rebar in the concrete is all stainless steel which should extend it's lifetime by quite a bit. The concrete itself is a special high strength mix. They really spared no expense after the mess that was the last bridge. I think that politicians have learned their lessons. There's a massive infrastructure renewal going on and there's really no opposition to spending the necessary money to make it happen.
@@jonathanlanglois2742 Tks. Great to hear. Love Montreal. from Newfoundland. Good work. good post.
@@jonathanlanglois2742 don't you all salt your roads to de- ice? Which is not good for concrete structures
@@matthewnewmann8555 All of the major roads are indeed salted. In fact, it used to be that the vast majority of roads would get salted. Nowadays, sand and gravel is often employed on more residential streets.
Great video. What country is this? Looks beautiful.
Australia - that big map of the country @0:12 is a dead giveaway
@@MikeT-TheRetiredColonel Lol. Exactly. Not to mention the accent. Wha a silly comment.
@@MikeT-TheRetiredColonel like the questionable habit of driving in wrong side of the road... 🤔

пздц. У нас в подмосковье подобный мост полтора года строили) Какой асфальт положили в итоге усаться можно)
Great video, great time lapse, great detail and commentary..
Did I say great video..? ;)
WOW - The amount of words needed to build a bridge is mindblowing. 😊
You have the same system as we have here in the UK small number working, large number watching .A good foreman is all you need and the working men could easily run the site between them thus reducing the need for the watchers and reducing overall cost
Shit that's anywhere lol
That 500 ton crane couldn't lift that little bit of wood you kidding me.😂😆
The crane wasn't assemble a its maximum lift capacity at the beginning.
350 ton
The crane will lift 500 ton like right next to it, not 50 meters away on the other side of the river. So, get an even bigger crane in there (not possible without major earth works), get the crane midriver (not possible due to flood issues/ needs major earth works) or decide to split the load in two, and save some money in not having to go full monty on the crane, dufficing with the 350 ton package.
Besides "hat little bit of wood" are you kidding me, wood is heavy!! Especially the dense hardwood species needed to construct a bridge that lasted 100 years (give or take, didn't pay too much attention to the years mentioned).
Fare better than the chines !
Cool
Duff’s bridge is good strong and construction past now
Most excellent videography !!!
Kinda wished the old one was left as like a foot traffic

Very well done. Civil engineeering at its best.
Great video I like the walk threw as it plays
Waw, I enjoyed to watch.
WELLDONE BOSS
Wow that was a great job! Good work.
music sucks
We do that on Interstate Bridges.
Hope they repurposed the wood for flooring and paneling.
if you think that rotten junk was usable for panelling you're crazy, they obviously re-used what they could (15:40)
Great job👍👍👍👍👍👍
Nice project!
Well done all.
Well done.

Marle brigde ,where is country??

I could not tell how deep the the concrete and steel piers were. Nor could I see it on the drawing. How deep were the piers?
5 minutes into the video, THREE METERS MATE.....
Мост вроде метров 50 в длину от силы, ровное основание из блоков.
Но на последних кадрах - весь асфальт волнами.
Placing the new bridges right next to the old other would have saved several million from each bridge. It also would have allowed both routes to remain open without closures. There is no advantage to building a new bridge in the old bridges location.
Wow, several million from each bridge? You do realize that it cost $16 mil combined, right? And this is way out in the outback where the bridge closures had little effect on traffic. I'm guessing you were an engineer on the project, right? Oh, wait, you're a keyboard engineer - 'nuff said
@@MikeT-TheRetiredColonel Uh, i saw $6 milion in the end for cost, not 16 or is that ausd vs usd?
@MidnightVisions you watched the video? they intended to build a new approach and all, but some wildlife species blocked that new route. And since they didn't want to throw away another design (and dollars) when more wildlife was found, they chose this option. (first advantage)
Also mentioned at least twice, reusing the trajectory means little to no work needed on the approaches to the new bridge, compared to the long reroutes needed for the bridge in the river curve.
So that saves money (second advantage allready),
Not related to the actual bridge location, but testimony to how considerate they were to saving moeny or spending it wisely:
Initial goal was to build for $5 mil, tenders where put out at $12. They where thanked for there input and ignored.
The contractor asked to do the job was smart and designed one bridge to fit both locations, and delivered both bridges for $6 (or $6,8) mil dollars on and partly ahead of schedule.
The old wood was reclaimed. (which will have granted some money back)
And finally the temporary steel carrier structure built under the old bridgedeck and reused under the second, was designed to be usefull in case the county needed to replace a washed away bridge in case of emergency. So money spent but not on steel to be scrapped immidiately after the project.
On such a big project to say there would have been a saving of "several milion" on a total of just 6 milion is plain stupid. (Even if i am mistaken and it cost the 16 milion MIke the colonel talks about, several milion are impossible to shave of the project)
I enjoyed watching thst works. Smart solution. Too bad that I could not finish watching it due to the undesirable nerve
Wracking background music.
talk about blowing your own trumpet!
Trump’s followers?
Proper response is: thank you very much for informative video. In reality everyone who publishes a YT video is blowing their own trumpet or calling attention to themselves in some way.,
@@cdouglas1942 if you say so automaton
What a shame that timber frame was replaced with concrete
100 year old bridge that would burn in an instant considering how things are down under - you have to think ahead for the next 100 years
Sadly timber bridges are too costly to maintain and thier design life wouldn't be as long
Their driving on the wrong side!
The federal government budgets for infrastructure whether you use it or not. Why are you wasting local monies?
ужас, зачем столько слоев асфальта? вот у нас кинут 1 лопату и размазывают ее, а цена как за 20 тон, не умеете воровать видимо...
I see the competition bridged a piece of old junk pottery and stop the bridge.
someone rebuilt a wood bridge, it aint wood anymore, the end.
Crane on stand by = $$$$
Video is great. Commentary drove me nuts.
