We argue that the restructuring of this infrastructural domain has been contingent upon geographically embedded trajectories stemming from previous historical periods, while leading to the creation of new socio-technical lock-ins. The paper thus develops the notion of "rolling path-dependencies" in order to explore how post-socialist developments both overcome and supplant previous trajectories of transformation. It focuses on the northern Czech town of Liberec -a place that is known for having some of the highest heating prices in the country -to elucidate how a socially, economically, and environmentally detrimental lock-in has come into existence as a result of illconceived policies of marketization, municipalization, and privatization. Using evidence from official documents and interviews with policy-makers, we demonstrate how the infrastructural legacies of post-socialism both persist and are being reproduced at the urban scale even within "advanced" reforming states like Czechia.
