We traveled 270 east of Hot Springs both last fall and this spring going to and coming from Alabama. We were pulling a 35ft travel trailer and had no issues.

I don't know of a highway 1530 in Arkansas. There is HWY 70 out of Hot Springs to I-30 and it is a good road. Then there is HWY 270 out of Hot Springs off of hwy 70 that goes to Mt Ida. Can you tell me what map you're looking at and maybe I can help?
