Here one other thing that I want to tell you is that M3 which was opened for public from 30th March of this year has not any service area and petrol pump functional yet. Only washrooms nearly Sumandri are opened for public. It is also advised to keep your petrol tank till half before entering M3 motorway. Same situation is also here for M4 from Abdul Hakeem to pindi bhatian.
Also keep this factor in mind, if they operational M5 then may be you face service areas and petrol pump issue for 6-12 months after its opening. We all know very well about the peace of progress of NHA. They have even not yet given advertisement to hire new staff for M5 motorway.
Let see and hope the best. I would like to suggest to use your traditional way till multan or khenewal for this year. But in next summer you will have better option with maximum facilities
