Infrastructure is the backbone of STRING, as the creation of physical meeting places and the free movement of the regions inhabitants, goods and services is key to creating a functional integration. STRING is working with analysis and networks to be able to prepare political statements, advising the regional politicians on what decisions to make in aid of an accessible and mobile infrastructure corridor.

In order to improve accessibility and mobility, STRING wishes to create an active political dialogue around the infrastructure needs and necessities of the STRING region.

A key issue to debate is the bottlenecks in the infrastructure system between Scandinavia and Central Europe. Bottlenecks are locations that will affect the traffic flows to and from the Fehmarn Belt link, and that therefore has an effect on regional accessibility and mobility. Such bottlenecks primarily affect road and rail transport. An upgrade of the network infrastructure in the entire stretch from Öresund-Hamburg could be necessary, in order to assure the possibility of easily reaching destinations both within and outside the STRING geography. 

Having an interconnected region is absolutely key to all other aspects of integration, as well as to utilising the economic development presented by the fixed link. It is therefore important for the STRING partners to discuss ways of eliminating infrastructure bottlenecks. 

The status for high sped networks in Northern Europe also ranks high on the STRING agenda. Triggered by the Fehmarnbelt project, there are on-going discussions on the future perspectives of a high-speed link between Hamburg and Copenhagen. This vision is intended to make the mobility of people between the two metropolitan regions more secure, more efficient and more environmentally friendly, with priority given to social and territorial cohesion and economic dynamism. Until now there is no existing high-speed link between the Central European network and Scandinavia.

As one of the main objectives of the STRING cooperation is to find sustainable improvements in mobility, i.e. having more transport of goods and people from fuel consuming to energy saving transport modes, the future integration of Scandinavia in a trans-European network for high-speed trains plays an important role in today's (political) discussion.
