Why? Liability. I have very little tolerance for the risk of liability.
I have no idea who built it, what they accounted for in the design, who owned it, etc. But, if i were the cash strapped owner of the road, and, say, 5 years from now, the road blew out over the culvert? Its very easy to blame "oh, the guy downstream put a screen up which blocked the debris and caused the culvert to fail, so he should have to pay". True? Who knows, and who cares, but road fixes are expensive, and usually the last person to touch something is the one blamed.
Honestly, if i were redesigning a culvert, i would always make it bigger than existing - no one complains after the first financial pinch about the bigger culvert, but bigger culverts are less likely to trap debris, and less likely to fail. And are easier to clean. And culvert maintenance is something many places skimp on. Not to mention if the road debris head downstream onto your property and damage something... Nice to be able to blame the road owners and maybe have insurance pay something.
Anyway- i would personally do whatever you want do downstream of it (within reason and safety), but leave the liability for that culvert with the road owners. I like baffling erosive flow to slow it rather than trapping it, in most cases, which slows water down to make it less powerful rather than allowing it to build up (safer in an unengineered solution).

On reflection messing with something thats has done well for so long may be unwise.
But maybe some improvements can be achieved where the erosion is and all will be wqll

I have a situation a little like yours but less extreme and I have been able to slow the water to a degree with exactly what has been discussed, brush dams.

In your picture it looks like the side you partially closed off is the downhill side but I can't tell for sure. If it is, I would move it to the uphill side. The thought of causing silt and debris to build up inside your culvert and having to clean it out is unappealing at best.

Those two half barrel or just one as your limited on space become a bench "bell".
Use preferably bricks, to surround the "bell" cover with mud. You have mud right?
