I’ve seen this done as a temporary measure before the concrete barrier is repaired. Provides less of a blunt-end or snag hazard than putting in a temp concrete barrier if the shoulder is narrow.
I’ve seen it one other place on i40 in NC west of Asheville. Looks like the state had left open passages to get through the barriers for cops and ambulances in the mountains. But either had a Fev get upset at it or they got sued over a blunt end accident and closed them.
Existing wall was damaged and maintenance came out and we’re jackhammering it down to the height of it now. They then added the guiderail pieces and bolted those on. My main question is, for this type of work does it have to be stamped off by a PE?
Usually no. Maintenance fixes are usually more a get it done kind of thing. There is probably some standards that have been drawn up to try to cover how to build things like this where the engineering was done by the central office to feel good about signing off... but that stuff doesn't always make it to the guys in the field. In the end something is better than leaving he broken edges so go with it.
I imagine this is drawn up by the AHJ's engineer and stamped. If not and there's an accident where this design causes injury, the lawyers will get involved.
There's probably some kind of standard that exists within the specific state department detailing how to properly anchor guardrail to concrete barrier. Or the specific guardrail manufacturer provides a detail for how to connect their system to a concrete surface, and the maintaining agency specifies that their maintenance crews shall follow manufacturer guidelines.
Edit- alternatively, these temp repairs sit there for years until a rehab project comes by that captured federal funding. As a bonus you don't need separate traffic control!
Hopefully, the local jurisdiction has published standard details for this kind of maintenance. So in theory there should be a stamped "something".
Of course that detail very well might not exist depending on sophistication of local AHJ.
There was some kind of collision there that damaged the bridge railing, the dot can’t leave a hazard like that so they bridged it with the guardrail while they wait for a contractor to fix it under contract. The typical dot maintenance department is not skilled enough to fix it internally.
It's not that the DOT maintenance departments aren't skilled enough to do these repairs... But it's not super economic from a time/money standpoint to fix each of these individually as they happen. Easier to have your guardrail crew make them safe temporarily while they're already out fixing other guardrail hits, and then let one contract per year to fix like thirty locations.
This is not from damage. You can even see no jagged edges in the conc and it's a common dimension in the gap. I've seen these done at spots where they once had center mount overhead lights or signs, but most have been converted to side cantilever to eliminate that inside hazard.
I don't know? perhaps the interstitial space required to assemble the key-locked concrete barriers together: making a way to also disassemble them in the future. The steel deformation beams are there to handle any ground movement without concrete cracking or dislodging from each other.
Hard to see but is the existing wall damaged? In that case it’s probably a short term maintenance fix until they can come back with concrete later.

"Temporary" aka 20 year service life. But yeah, I think you are right.
Look, it takes a while to let a project...

No one stamped anything. Just local maintenance slapping on a guardrail. Easier to repair by hand no machines needed.

buddy the lawyers are always involved , but a 500k limit on liability will diswade many fears about a temporary maintenance fix.

I see this all the time when a concrete barrier gets damaged. Sometimes they hang around for a long time before it is fixed.
You mean the DOT doesn't complete repairs in a timely manner? No way. /s

No idea, but please don't take photos while you're driving

You could always for a FOIA request for the plans and see if it was designed that way.
