Time lapse of 58 hour bridge replacement.
 

https://youtu.be/AzHEMxcizcI

Time lapse of Tennessee DOT taking out old bridge and putting in new one in a weekend in downtown Nashville.

That's crazy

Unfortunately, it takes 58 days to get the same amount of work done around here.

This would take 6 months in Missouri. :rolleyes:

That's because in Missouri they would tear down 6 bridges over the weekend and alternate which ones to work on based on the astrological sign of the foreman for that day.

No it wouldnt, both Missouri and Kansas have done similar projects. By the way the DOT's don't build bridges hardly ever if at all. They hire private contractors to do the engineering and construction. That is not a complicated bridge at all its not over a body of water nor did it require piers. The abutments appear to have been reused so no regrading below them. Single precast concrete beams and and other than the approach aprons at each end the bridge no regrading of pavement was necessary. Really people who have no idea what a project in construction involves should not comment on what it takes. Its like me not having a clue what your job involves criticizing on why it took you so long.

No shit!

Example of a simular bridge in Ks that took 58 days to this rehab in Tenn. ?

They'd just slap a giant steel plate on top of that sumbitch for 2 years first....

That is such a Sagittarius thing to say.

Dammit. I'm a libra and do not know how to respond.

Having driven through Nashville several times early last year, Downtown was a cluster**** because of construction. Kinda wish I could see all of that completed.

FYP.

Construction or no, traffic is always a cluster in Nashville.

ROFL

It is everywhere most the highways were designed for 1950's traffic. Well we now see that has expanded astronomically. So highways were designed with a 30 year lifespan with not nearly the load that is put on them now. Over the road trucks responsible for beating done sub-grade on roads have has weight limits and size extended. So yes they are failing badly 65 some years later. Yet we want smooth unencumbered drives to work but don't want pay for or have patience to put band aid on what we do have. I think they are pretty damn good considering.

Take two ****ing year to fix a bridge here in tulsa!

Can't even get contractors to show up on site at the bridge construction on I-70 near 635 in Kansas. Took a lane away while no work gets done.

Did they really use precast slabs to span the bridge? What's the expected life on those?

Libra's never do...

not sure ont he specifics, but I think they can get away with that down south. Not around here.

Yep and its pretty cool isn't it. You eliminate all the ironwork assembling rebar and tie wire wrap. and concrete flat work and curing. Just like a paver you remove old paver and put in new when damaged. As for life span I suppose its as good as any bridge. Hell cobblestone roadways were so good many town squares just black topped over them.

This is probably very true. Wasn't really thinking about the region.

Bridge decks are poured in place panels vs placed in panels such as that video. The concrete will get construction adhesives sprayed on it just like any concrete slab. Also the concrete consistency and strength can be poured in a precast plant with far better consistency than a ready mix and delivered wet to site. As for winter life from freeze and thaw id expect to be about same it has expansion joints and coating just like any concrete slab.

You could do a time lapse video of construction in SW Kansas and it would look like a still photo.

Weak link may be in the grouting could get labor intensive. But is probably offset by fact that repair will be fast and easy with minimal lane closure due to no cure time.

Its been done in Missouri and HNTB was all over it.

The proposed I-70 smart highway across Missouri could all be built with this method of construction.

Damn impressive.

Just found out a road will be closed for a year for bridge and pave work.

You do know that the people who build those bridges come from all over the country. It has nothing to do with states or local. What is important is complexity and scope of project all are different. Take a picture of this bridge and post it. I will point out why that bridge is most likely not remotely similar to the one in this post.
I would be willing to bet in your job you could post something that looks just like another something and I could say well why so long for this and not that.

The section of I-44 that crosses I-49 has been ****ed all summer such that the lanes are so tight that if you're in the left one you're driving on the rumble strip for a solid mile if not three. That goes for both directions of traffic.

There is always the know it all that comes running out the door in his robe and slippers top tell you how it should be done and why your doing it wrong.

We call that guy the sidewalk engineer.

Send the bill to MODOT get a free alignment they will just pass it on to the contractor who was supposed to grout and smooth the rumble strips.

Not sure if that would fly considering they have signs advising drivers to stay in the right lane to avoid the strip.

I hate those things all they are good for is knocking off wheel balance weights and screwing front end alignment.

If your a dumbass and fall asleep at the wheel you deserve to run off road into a ditch or tree and burst into flames.

It does not take much watching to realize MoDot are worthless turds stealing money on the clock. I am sure there is maybe a couple quality workers there out of the entire bunch.

I think people feel that way because of projects like the Grandview triangle-which took 20 years to build. Texas built the entire George Bush Highway in that time. In my area-they had Noland bridge over I70 messed up for 2 to 3 years. Sucks that you have to take the blame for slow contractors.

I also think people get their panties in a wad when there are major traffic jams-then you go by the construction site and 20 guys are standing around holding shovels or smoking.

You are correct-it is all about perception-and unfortunately - past projects have been slow with shoddy work. Example-the repave all the way down 23rd in Independence was complete shit. They still haven't fixed the sidewalks after all these years. The overlay was a mushy mess. The islands were not fixed and pieces wash into the road during heavy rains.

It might not have been MODOT- but I am sure they will get the blame.

Kiewit, the company I work for in Lenexa, has done this many times in the last few years.

I wish they would of slowed it down a little bit..I never could find the 8 guys leaning on shovels while 1 was digging

Not a bridge, a street through town.

11 months for 3/4 of a mile, and the same crew is doing several towns at once.

They are right down the street, and it is the standard 5 guys watch one guy work, which is during the 3 days of the week they are there.


I don't blame them. 100 degrees and 80% humidity is tough.

I am not bitching to bitch. I work my ass off for a living, and I know their job it tough, too, but there is a LOT of wasted time on the jobsite.

Did utilities above and below ground need to be removed and replaced? Did right of way need to be purchased. Did new storm and sanitary sewers have to be built. Did a grader uncover a arrowhead and site shutdown till archeologists scour the site to make sure it wasn't ancient burial ground. Did grading contractor find contaminated soil from a former gas station no longer there and the EPA stepped in. This is a myriad of just a few things that happen and slow construction.

I'm not employed by MODOT I am a private land surveyor. I have been contracted to do construction staking and preliminary design surveys for them. I don't see what you claim though most work like anyone. Most of what people see are contractors working for the DOT's I suppose if they are leaning on shovels that possibly they are waiting on concrete or materials.
As for maintaining right of way, removing snow or dangerous debrie or a dead animal the do well.

Kiewit is a good company I worked with you guys at Iatan II power generation Plant contracted by KCPL.
