Bicycle accident, road rash. Injuries missed work. Any advice?

Next time don't go too fast for conditions. Never go so fast you can't avoid obstacles in your path. And with a red light looming, no less.

I'm not sure quite what question you are trying to ask. Do you want advice on how to ride safely, medical advice or financial advice?

There’s not even a proper question here!

You don't say exactly how steep the hill was. I live in a mountainous region. Several places have lengthy 30%+ grade hills that requires stops at the bottom of the hill. Locking up your brakes on rough pavement going down a long steep hill is the worst thing you could do. What you need is a bicycle computer to monitor your speed. Then bump brake just enough so that you slowly descend the hill.

On the trail at Cades Cove here in Tennessee they advice renters at the cycle shop to walk their bikes down the really steep hills.

All I can say is that you were not careful enough applying your brakes. When approaching a traffic light at high speed on a downhill you have to start braking as soon as possible, gently at first making sure that your tires have sufficient traction. When you brake, move as far back on your saddle as possible and straighten your arms so that you are not thrown forward if the wheels lock up. Keep your body as low as possible and as far back as possible

However, this question is unclear about what sort of advice you are looking for. On one hand, you may be looking for advice about how to hold someone legally responsible for the road conditions that you seem to think caused your fall. To prove something like that, you need local help. You need to enlist local riders who know that road, preferably expert riders some of whom have also fallen on that road. You will need a lawyer willing to find road safety experts willing to testify that the newly resurfaced road was inherently dangerous.

So, what is your goal? Are you trying to prevent future falls? There are innumerable bumpy downhills. You have to learn how to deal with them. Fixing this one won't help you with the next one

Had this been an auto accident, would you have asked under Cars & Transportation? It's a medical question. Belongs somewhere in the Health section. Not the brightest idea to ask for medical advice from complete strangers on the internet.

Go see a doctor.

Take 2 aspirin & call me in the morning. You'll be fine. Oh...and maybe see an eye doctor for some glasses.

Thank you for doing your part for the environment. Now go to the doctor and get some pain pills.
