How can you get on 93 south from the 93 north pl;aza?

Head north and take the next exit and follow the signs for 93 South. It's about a 4-mile u-turn.

Jane I don't believe you Can! You need to take the next exit.

Gotta exit and turn around

As far as I know you would have to continue North one exit and then turn around getting on to the southbound side.

No.
