The route starts at Phuket International Airport, with the initial section being an elevated structure along Highway No. 4031. Then descends to ground level at Highway No. 4026, before elevating again to cross the airport junction and underpass. After making a right turn, the route returns to ground level along Highway No. 402 to enter Phuket City. The alignment transitions into an underground tunnel for approximately 3 kilometers at Thalang District area. Then re-emerges at ground level, passing the Heroines’ Monument (Thao Thep Krasattri – Thao Si Sunthon Monument).
