The master's thesis presents four preliminary variants of the ŽC6226 road reconstruction design, section between Dubrava and Žuljana on the Pelješac peninsula in the Dubrovnik-Neretva Region. Designed road variants are generally aligned to the existing road in accordance with the current Croatian Regulation (NN 110/01) for design speeds of 50 to 70 km/h. The lengths of the designed road variants range from 4540,75 m to 4615,20 m. The horizontal alignment of the designed road variants consists of 6 to 9 straight lines and 19 to 20 curves with a radius of 75 to 350 m. The vertical alignment of the designed road variants have a maximum longitudinal grade of 7,59% and a minimum of 0,30%. In all road variants, the width of the traffic lane is 3,0 m and the width of the paved shoulder lane is 0,2 or 0,3 m depending on the design speed. A sidewalk was designed on the left side of the road at the entrance to Žuljana. Stopping sight distance was tested on all variants of the designed road. It turned out that on all variants, in some parts, sight distance requirements were not met and that the side slope had to be widened. As part of the project assignment, preliminary design of a three-leg road intersection was made at the intersection of the designed road and the existing road DC 414.
