This project, in which five project partners from Mecklenburg-Western Pomerania, Brandenburg and Poland are involved, aims at the development of transport infrastructure in the German-Polish border area of the Euroregion POMERANIA. The project includes investments in cross-border transport infrastructure and mobility, which contribute to the integration of the assisted area and its better connection to the European area as a whole. All road construction measures in the project have a cross-border impact on the assisted area and are located in the border area. The urgent and necessity of the measures results from the need to strengthen cross-border transport in order to promote the joint economic and social development of the region, to improve the development of economic and tourism transport objectives and to further develop significantly touristic transport infrastructure. The overall project is requested in two sub-applications that are directly related. Both sub-projects are based on an overall study and a common transport approach to improve the near-border infrastructure. The overall package of measures ensures that development quality is significantly improved throughout the region and stimulates further economic growth. The measures and their effects are therefore always to be seen against the background of the overall package. The expected project result is an improvement in the quality of cross-border road transport. The planned measures are of particular importance in the regional road network, as they continue to contribute to the significant reduction of travel times, especially on cross-border relations. Implementation of the measures will improve the external accessibility of the entire region and the links within the programme area. This provides impetus for the further economic development of the area. In addition, the cross-border accessibility of places of work and residence for the population of the assisted area will be improved. It will also make an effective contribution to strengthening cross-border contacts and communication, as the mutual accessibility of people in the border area will significantly improve. The development of tourism in the region also benefits from the improved accessibility and the attractiveness of the transport infrastructure relevant to cycling tourism. In addition to the economic and social effects described in the project, it will also contribute directly to improving road safety in the road network under consideration, since it is accompanied by a compliant and therefore state-of-the-art design of road infrastructures. Improving the structural status of road sections can also reduce the negative impact of traffic on the environment. This project is a result of intensive coordination between road construction administrations in Mecklenburg-Vorpommern, Brandenburg and West Pomerania Voivodeship. The road conversion and refurbishment measures concern road sections with a cross-border impact, thus cooperation between the Polish and German partners is necessary. Previous investments in road infrastructure were predominantly local and related only to a part of the region. The new solutions that have been applied in this project take into account the perspective of the cross-border area as a whole, enhancing the synergy effects, the usefulness and sustainability of project results.
