The Butile Loop was designed as a three-tiered loop which ensures the smooth flow of traffic in the following directions: the Sarajevo Bypass that moves in the direction of Zenica-Mostar – the Sarajevo entrance/exit in the direction of Zenica and the Sarajevo entrance/exit in the direction of Mostar.
So it is now possible to access the A-1 Highway, the route of the Briješće Roundabout that moves toward the A-1 Highway, as well as the section of the A-1 Highway-Briješće Roundabout. The section of the Sarajevo Bypass LOT-2 has two subsections: Lot-2A (Butile Interchange-Briješće) and LOT-2B (Briješće-Stup).
The loop is made up of four ramps (A,B,C and D) and the entry ramps that go toward Briješće span a total of two kilometers.
The total length of LOT-2A is approximately four kilometers and the open section of the full-profile highway is about 3 kilometers long. LOT-2B has two separate roads with two lanes each which have a total length of about 500 meters.
