You cannot produce pre tensioned beams just by pouring beams at the side of a road; you need a factory setting for that
Well I beg to differ. It's done all the time.
Obviously not by the side of the road, but on prepared flat pads with a concrete working pad on top.
From what they are doing it looks like they won't be any casting large or complex beams or girders

But I have been on projects where it is done. Several projects in Saudi Arabia on which I was an engineer were done this way.

Obviously they will pour their columns in place on site and the girders will be poured on top of them. As to what kind of support beams will be placed atop the girders to support the bridge deck is the question.
By the way there is some long vegetation growing through the rebar cages so they have been on site for several weeks maybe more than a month, - well ahead of the award of contract.
So I guess the Contractor was pre-selected, if he was the one tying the steel cages.

But we are over-thinking this work.
It is going to be an inexpensive and not very attractive bridge - really an overpass is all it will be. Not very creative.
The old bridge had way more charm, and seemed like a portal to the North Coast.
The new one most people won't even notice.

I'm betting this is what we're gonna get:

That’s for sure..only post tensioned on-site can be done..
I've been on projects where both are done on and off site. Post tensioning is cheaper. And can be done in place on the bridge with portable tension jacks.
So both can be done on-site or in a casting laydown area or at a fabrication plant.

Just Heard.....From local Colmado
3 injured 1 dead as someone went over the Cangrejo bridge..... didn't want to read the signs I guess....
Condolences to the family ,

but I blame the GPS..
it probably kept saying Derecho derecho ... and they ignored what was in front of their eyes ..

The signs there are very misleading. There's still one sign that indicates light vehicles only continue straight ahead and another that says heavy vehicles and trucks take the detour. Many times I've seen vehicles coming from the direction of the bridge which might lead some to believe the bridge is there.

It says they had left the disctec in sosua and that the 3 showed signs of alcohol. Do you think the other one was sober?

Self inflicted, as the article explains.
Young Dominican, late at hight, party/alcohol? aggressive driving.

Testigos oculares del accidente, narraron que el fallecido y los otros tres jóvenes viajaban a bordo de un carro Honda Civic de color negro, que se desplazaba supuestamente a gran velocidad llevándose por delante varios tanques y obstáculos que habían sido colocados en el lugar para evitar la circulación vial.

Fortunately other innocent people were not killed or involved in the accident.

The third best country to retire, maybe if you stay at home after dark for your own safety.

Now they can get back to work building the bridge after the power lines were moved and the car removed.
