On 13 October 2018, the Bratislava region, as the managing authority of the INTERACT III cooperation programme, organised the 6th European Cooperation Day. This year's theme was the idea of building our shared future. The event took place at a symbolically important venue, the Freedom Cycling-Bridge. The bridge was co-financed by the Bratislava region under the Slovak Republic-Austria 2007-2013 cross-border cooperation programme. Only 30 years ago, the river the bridge now stands on formed the iron curtain that divided Europe for many decades.

The event attracted both young and old, with a number of activities for children. These included a performance of the musical Ice Kingdom by the Bratislava puppet theatre, a workshop on painting our shared future, horse-riding, and an educational activity, 'Europe in fairy tales', where, after successfully completing each task, thematically linked to EU Member States, the children received a stamp as a reward for their hard work. The event also featured various popular Slovak bands.

The organisers also managed to break the record for the greatest number of people who crossed the bridge in one day. On 13 October 2018, 3,591 people crossed the bridge – a big increase on the 1,664 people who crossed it the year before, and the 742 people who crossed it in 2016. On this occasion, the President of the Bratislava self-governing region and ECR Group Member, Juraj Droba, said, "We have chosen this place as the venue because it is symbolic. Some years ago this place was marked by borders that divided free Europe from the rest. Today it is a point of connection that links Slovakia and Austria. It is important to talk about history, to remember and recall it and to emphasise that it is cooperation that will play a key role in the future of generations to come."
