The rapid development of suburbanisation in Bratislava has led to an increase in the number of people transported daily between the hinterland and the city. Intensive traffic flows and the preference for the use of passenger cars cause regular congestion on the roads between the city and the hinterland as well as within the city. On the basis of the above situation, there was a need to create a connection of the eastern suburbanisation belt of Bratislava to the D1 motorway in the Triblavina area (the “D1 motorway Bratislava – Trnava, the Triblavina intersection”) which will result in a rapid reduction of traffic loads on the existing road network. The construction of this building will positively affect the traffic situation in the territory. This will eliminate loss of time for drivers and passengers and significantly improve the transport comfort of road users. The planned communication represents the fastest connection of the area of Pezinok district with the D1 motorway as well as with the city of Bratislava. The target group is mainly residents of the surrounding affected municipalities, namely Croatian Grob, Vajnory and Slovensky Grob, since the communication in question will significantly relieve traffic in these municipalities, thereby contributing to improving the quality of life and improving transport accessibility. In terms of measurable indicators, the aim of the project is to build 1.7 km of road and to obtain savings in road transport time on a newly built road section of EUR 856744 at the end of the project implementation and this value increases annually in terms of the CBA.
