deleting highways and then tracing them anew is seldom a good idea since many a road is part of some network of relations which then get broken.
I believe (or hope) that the easy fix to the routing problem you encountered is a simple "no left turn" restriction.

I do hope I fixed your attempt and now everything works.
Routing may take a while to change, depending on the software used and the update cylce.

safe travels
