The graduation thesis treats the linakge – road Sečovlje – Izola. More exactly it discusses two new alternative ways from Padna to Sečovlje and compares them with the existing route R3- 628/1427 Sečovlje – Dragonja. The planning of both new variants is based on the road designing rule-book and is completely designed by a computer program. The area between Izola, Sečovlje and the valley Drnica has an unique potential because of its favorable geographical and traffic position. Even if it is mostly part of the community of Izola it is actually the background of the three most touristic cities of the Slovenian coast; Izola, Piran and Portoroţ. The existing road network is insufficient and undeveloped and there is lack of traffic communication between the coastal cities and the countryside. The main problem of the route Padna – Sečovlje is that runs on hilly area and it confines with hills on one side and large agrarian valleys on the other side, therefore the use of tunnels is obviously considerable. The comparison was prepared on basis of traffic, technical and cost criteria with consideration of the influence on the environment and regional development. The results of the study show us, that the variant 2 of route is a slightly more appropriate than the variant 1. Even though it is economically less acceptable it has better technical elements
