The Ngadirojo Hamlet Road section, Sooko sub-district, Ponorogo Regency is part of the development of the cross-district road network in Tunggal Rogo Mandiri which includes Tulungagung Regency, Trenggalek Regency, Ponorogo Regency, Madiun Regency, Kediri Regency and Nganjuk Regency in order to expand the economic system. In general, the traffic lanes in Ngadirojo Hamlet, Sooko District, Ponorogo Regency are very inadequate because the traffic lanes are partly rocky and not wide enough, therefore it is necessary to develop road geometry. This development is to improve road geometry, road pavement thickness and Budget Plan (RAB). The road section is 727.11 mm long with a width of 2 x 3 m and has a shoulder of 2x1 m and has three curves, all of which use the Spiral-Circle-Spiral (SCS) curve type, the first curve has a value of Rc = 150 and Lt = 122.44 m , the second arch has the values Rc=180 and Lt=103.45 m, the third arch has the values Rc=133 and Lt=190.39 m. The thickness of the surface layer (Laston MS 590) is 5 cm thick, the lower foundation layer (Class A crushed stone) is 20 cm thick and the lower foundation layer (Sirtu Class C) is 15 cm thick. The planned budget for this development is IDR 1,243,213,155.17.
