Road removal + tram spine
Street to city conversion model
From the mid-2010s Odense Municipality in Denmark pursued two linked transformations: the conversion of Thomas B. Thriges Gade, a four-lane road driven through the medieval centre in the 1960s, into a car-free quarter of housing, cultural buildings and public space above an underground car park; and the construction of the Odense Letbane, a tram line opened in 2021 forming a new public transport spine through the city. Together they reoriented Denmark's third city from road capacity towards walking, cycling and tram-based mobility.
The Thomas B. Thriges Gade project has become a European exemplar of motorway-era road removal and 'street to city' repair, demonstrating that reversing 1960s traffic engineering in a historic core is both feasible and popular. Paired with the tramway, Odense illustrates the mid-sized city version of the sustainable mobility transition that has shaped Danish and wider Nordic planning debate.
