1. General information
2. Objectives of the intervention
Goals of the intervention
(a) The main objective of this plan was to construct a "Green bridge on highway D2 - Moravian Sv. John under the project AKK Basic "(AKK - the Alpine Carpathian Corridor) in the cadastral territory of Moravian Saint John, in the territorial district Senica.
(b) To create an efficient passage for migrating animals over the motorway D2 and to prevent the animals to run into the highway, where a conflict of motor vehicles has frequently resulted in the death of animals.
(c) to protect the species: European badger, otter, wild boar, roe deer, deer plain, red fox, gray wolf and lynx.
(d) Furthermore, To address the issue of isolating populations and subject them to the area's significant climate differentiation. (5, 6)

Quantitative targets
- Edge of ecoducts' slopes offer the possibility of setting up small retention of water reservoirs or rainwater to a depth from 60 to 80cm.
- Reduction of the number of wildlife roadside accidents. The number of wildlife roadside accidents surveyed between 2002-2006 was 205 at the D2 motorway in Záhorí. (5, 6)

Sustainability challenge(s) addressed
Habitats and biodiversity conservation: What types of conservation goals are / were defined for the NBS intervention?
Habitats and biodiversity conservation: What activities are implemented to realize the conservation goals and targets?
Implementation activities
Construction began in 2012 when traffic was strictly limited on the D2 highway connecting Bratislava, Brno, and Breclav. The implementation procedure was divided into six stages. The first stage was carried out under pilot production; the large-diameter side panels of the bridge were removed without traffic restrictions and the production of the precast bridge super structure also began. In the second stage traffic was restricted to the direction E and the SK-held embodiment of the piles below the central support. In the third stage, half of the supporting structure was assembled and a side part-pillar and arch panel and wings were installed in 10 days. The fourth stage transferred the transport direction with the SK-E installed, and the second half of the supporting structure, pillars, arch panel and wing of the bridge were installed in 8 days. The fifth stage allowed traffic back again in both directions. The sixth stage did follow up work, including insulation. (3)

Type of innovation
Please specify technological innovation
This technological innovation provides support and sustainability to the maintenance of the region's critical sustainable infrastructure due to these areas being at risk of seismic activity. (3)
Novelty level of the innovation
Please specify novelty level of the innovation
The construction elements of the corridor provide a special seal commonly used for example in Japan, where the prefabricated flexible system with its thick longitudinal dilation and transverse distribution is immensely popular, since it is extremely resistant to the effects of earthquakes. This is important because the corridor is located in a zone of intense seismic intensity V-VI (on the macro-seismic scale MSK-64). (3)
Replicability/Transferability
Please specify Replicability/Transferability
Germany and Austria are now planning other similar green bridges over existing highways. In the Austrian case, ASFINAG plans to build sixteen new green bridges between 2016-2027. The construction of this bridge on D2 was tendered for about €64,000 per m. while Austria's plans anticipate about €77,000 per m. (3)
