You are welcome AH, Mr Khan and Ali1. And while I am at it, let me also dispel a misperception regarding the interchange loop connectivity.
The first loop, the North loop, is fast nearing completion. The motorway fence has been removed for linking it with the motorway and work on construction of toll plazas has already started. This loop will be divided into two roads through a median wall. One road will be for traffic coming from peshawar side entering AWT. The second road will be for traffic going from AWT to Islamabad.
The second loop, South Loop, construction was initially started but then temporarily halted. I am told it is to commence this week. This loop will also have two roads. One road for traffic coming from Islamabad into AWT, the other for trafffic going from AWT towards Peshawar side. Its a complete interchange in every aspect. I will visit the site this week InshAllah and try to get the latest update and possibly some pictures.
