AOA dear all,
Well I tried the Ring Road!!! all the way back from Babu Sabu Interchange!!!
There is about 2 km stretch under construction as you approach Shalimar and Mahmood Booti Interchange! You will be diverted from Mominpur Road by the Army personel to the Main Harbanspura Road which will lead you to Bahar Shah Road, then you will reach the Amjad Ch. Road near the Air Port Run Way. All the interchanges are not carpeted yet. So be prepared for a really bumpy ride!!!

Approx. Image is attached. Ask me, that after the Diversion, it was not a pleasant ride!!!
Happy and Safe Driving!!!
Aqeel!
