The planning of this road is carried out on the section of Gedungan Gili Genting Island Highway in Semenep Regency with the aim of boosting the economy of the Giligenting Area, particularly in Gedugan Village. This road leads to Kahuripan Beach, which currently does not meet safety and comfort standards. Therefore, geometric planning and flexible pavement thickness design are conducted using the 2017 Bina Marga Method with the AASHTO 1993 Method. From the geometric road planning, a horizontal alignment is obtained with the first curve located at STA 3 + 500, with a planned speed of 60 km/h, a lane width of 3.5 meters, an outer angle ∆1=30°, and a Spiral Circle Spiral (SCS) curve. Based on the Vertical Alignment calculation, of Concave Vertical Alignment 2 and Convex Vertical Alignment 3. In the flexible pavement thickness design using the 2017 Bina Marga Method, the thickness of the AC-WC layer is 4 cm, the thickness of the AC-BC layer is 6 cm, and the thickness of the upper foundation layer (Class A) is 40 cm, with a total Estimated Budget (RAB) of Rp 4.350.255.857.. Meanwhile, using the AASHTO method, the thickness of the Surface Layer (Laston) is 15 cm, the thickness of the Upper Foundation Layer (Class A Crushed Stone) is 25 cm, and the thickness of the Lower Foundation Layer (Class A Gravel) is 12 cm, with a total Estimated Budget (RAB) of Rp 11.152.036.107
