Sorry for all the double posting (unfortunately not possible to remove), just was trying to answer my own question. I found this great blog: https://www.earthtrekkers.com/denali-road-closure-things-to-do/#:~:text=Denali Park Road is closed at mile 43%2C at an,causing the road to slump.
In a nutshell it says:
Many of the Denali’s best experiences lie beyond mile 43. Without being able to travel deeper into the park, you will be missing out on the best views of Denali and some of the best hiking trails.
If you only plan to visit Denali once in your lifetime, consider postponing your visit for a few years.
