Is this a temporary bridge? It was replaced because the old old probably was damaged or it collapsed or it was in really bad condition. But this is a really ugly bridge I have to say.

You may be correct in your suspicion.  That was one of several bridges along I-95 that were replaced due to low clearance, requiring some truckers to use alternate routes.  Unless there are plans to add the extra lanes in the median (one lane in each direction), the SR-1726 bridge over I-95 will need to replaced and reconfigured to permit widening to 6 lanes.

I assume you mean 8 lanes. Plans call for widening I-95 south of Fayetteville to I-74 to 8 lanes. It was originally proposed as 6, but given to the growth they bumped it up to 8. The widening in Lumberton was purposely accelerated due to the vulnerability of getting flooded. Hurricanes Matthew and Florence did that.

There you go.  Very few of the overpasses along I-95 will provide room for 8 lanes beneath.

Definitely not temporary…was refurbished to increase clearance in 2009.

Well this one was refurbished and raised too and it still looks old.

They didn’t use the same method on every bridge but personal observation is that they wanted to use the method in your last post’s link - raise the height with stilts. Sometimes that wasn’t feasible though the 2009 bridge may have been stilted first.

May I ask why you keep posting these as "I-40 Alt"?  I-95 is certainly more important than whatever goofy number Google shows it as.

Because when I copy and paste from my phone, that's what it shows. Again whoever added that to the map does not know what he/she is doing.

So, when bringing a freeway to interstate standards, this plan shows that the bridges that the main freeway bridge over will be replaced. They look fine to me... I don't see why they need to be replaced.

https://www.ncdot.gov/projects/us-17-feasibility-study/Documents/us-17-segment-6.pdf



All of the southbound bridges were built in 1976, so they will be pushing 50 years old when they get around to doing construction.

The northbound bridges were built in 1999.  Less sure why they would want to replace those at the outset unless they don't meet interstate standard in some way.
All of them are fine tbh even when they start doing construction. I don't see any reason to replace them

That section can easily be upgraded to interstate standards without having to replace those bridges.

how come these bridges have new parapets albeit old piers?
It either got a new deck (which comes with a new parapet) or was otherwise rehabbed with a new parapet called for in the contract.

This looks like a 1950s bridge, but from 2016.
How come this bridge looks newer, but is got older piers? :hmmm:

^^ I think he is referring to the style of bent/pier supports that is still used for bridges over water/wetlands mainly in certain regions.

Here is an official answer to your question.  This is a current VDOT bridge pier document.  Go to pdf pg 6.
https://www.virginiadot.org/business/resources/bridge/Manuals/Part2/Chapter15.pdf

Definitely other modern NC bridges have these...
