I currently drive to Malaga at least twice a month with our ALStrays Re-homing and Transport Project and while it is a pretty good run compared to how it was 10 years ago it will be significantly better once the Motril to Malaga stretch is open.
Seems that I will have to wait until 2015 for that to happen, as the government on Granada have confirmed that it will be completed by the end of 2015.
