I covered Joshimath to Badrinath ji.Thanks Satinderji as always for prompt response.
Have you traveled till Vishnuprayag or till Badrinath?
Previously I had seen road conditions significantly deteriorate after Vishnuprayag.
Roads were perfect.
I had same impression of 2010,
When Roads were bad after Pandukeshwar.
But this time it was totally opposite.
From Rishikesh to Joshimath, construction / widening of road is going on at non populated areas.
Tarred Road means populated area, drive carefully.
Unpopulated area means keep eye on non tarred road and drive accordingly.
Overall experience was good.
Take 1 night halt between Delhi and Badrinath ji.
Go till Rishikesh or ahead to Srinagar or Rudraprayag depends on your start time and daylight time left to cover the distance.
Accommodation is available at Badrinath ji in hotels and Sarai.
If by chance can't get stay, then try at Pandukeshwar or Joshimath.
I stayed at Joshimath and covered Badrinath ji in daytime.
Was able to Return till Karanprayag in daylight.
