Within the project task for the road M-17,3 Buna-Neum, section Neum-Stolac, several variants have been considered and the section has been divided into several sub-sections. The sub-section Stari NeumKiševo in the length of cca 3 km has already been built, as well as the sub-section of Kiševo-Bročanac, with length cca 8,5 km. Within the sub-section Bročanac-Drenovac, which construction is in progress, two main variants of the route have been set aside, namely the blue and the red one. The blue route starts from east of the Bročanac village, on mileage km 11+300 if counting from the beginning of the road in Stari Neum, and it follows the corridor of the existing road between Bročanac and Drenovac.
The red variant, as well as the previous one, starts from east of the Bročanac village, passes south of the Hutovo village, near the Glumin village, and approaches to the blue variant in the region of Trnovski brijeg. After that, it goes again towards south and over the Burmazi plateau it approaches to Drenovac, while at Varda it approaches to the blue variant and the existing route on north. For adopted blue variant there have been analyzed geomorphologic characteristics, geological structure, and hydrogeological and engineering geological, as well as seismic characteristics of the terrain. Reconnaissance of the terrain has also been done, and all previous documentation has been used as well as results of the former conducted geological investigations. As a basic point there have been used the Main Geologic Maps, papers Ston and Metkovići 1:100 000 with legends.
