We analyse the path dependent dynamics in the formation of new infrastructure using an augmented gravity model. We observe that the formation of the panEuropean telecommunication backbone has been dependent on pre-existent European transportation networks, particularly, the maritime and railway networks. Cities that were already central in these transportation networks were more likely to get connected through fibre-optic networks than other cities. Our study can be considered as a first attempt to analyse, in a quantitative manner, the path dependent dynamics in the formation of new infrastructure.
