Santa Nella CA to Austin Texas

Hi , I think it best for you to stay o I 10 ,when you reach San Antonio turn North on I 35 and Austin is 85 miles North. I you take I 20 get to Dallas , it take more than 200 miles to get to Austin on I35 South.

I would go south on I-5 to CA-58 to 395 south to I-10 east to I-20 in Texas and on to Austin. PM me if you need detailed Info.
