MoDusArchitects planned the expansion of the Bressanone-Varna ring road, including a sculptural new portal forming the gateway to the city of Bressanone, in the province of Bolzano. MoDusArchitects’ project reduces the volume of traffic at street level by creating an alternative route composed of interconnected roads which are largely underground, offering a model that might be replicated in similar projects in many other small towns.



MoDusArchitects Mobility, Architecture and Landscape in infrastructure design

A new portal with a sculptural opening and sinuous shape completes the recent expansion of the Bressanone-Varna Ring Road in the province of Bolzano, providing a new gateway to the city centre of Bressanone. MoDusArchitects’ project offers a good example of infrastructure that abandons a strictly technical or functional vocabulary to fit harmoniously into the landscape.
Inaugurated in 2012, the Bressanone-Varna Ring Road is now being expanded with the addition of another 8 km. The first 5 km, already completed, bypass the city centre of Bressanone to reach the north of Varna, while the final 3 km stretch is due to be completed in 2025. The purpose of the infrastructure project is to reduce pollution levels and motor vehicle traffic at street level by creating an alternative route composed of interconnecting roads which are primarily underground on the edge of the city, facilitating access to the industrial area on its southern side.
Architect Sandy Attia, who co-founded MoDusArchitects with Matteo Scagnol, comments on the project: “Civil engineering projects offer a unique opportunity to bring together the different scales and at times jarring specificities of infrastructure, landscape, architecture and urban decorum". Matteo Scagnol adds that “The role architects play in large infrastructural projects has been increasingly marginalized over the past few decades in Italy” despite the presence of urgent and important challenges due to the presence of a significant historical heritage stratified over time and fragile natural resources in need of protection.

MoDusArchitects’ project fits new forms into the traditional vocabulary of infrastructure projects, becoming a model for small towns needing to respond to similar problems with mobility and conservation of their heritage and identity. The architects identified three key principles governing the design of the technical elements (tunnel portals, retaining walls, acoustic barriers, service substations, mechanical structures, ventilation chimneys and signage) which had to be provided over the entire length of the infrastructure. Firstly, the design of above-ground elements with reduced environmental impact and high technical quality also had to express architectural quality. Secondly, both the above-ground and underground elements were designed taking into account the relief and particular features of the land, and therefore on the basis of a homogeneous approach which was not merely technical and functional. Lastly, the architects implemented a continuous solution, considered part of a single project and context, for the two segments in Bressanone and Varna. In technical terms, this approach meant a strong focus on reducing noise emissions and coming up with new solutions to environmental challenges; at the same time, the portals designed by the architects become expressive figures emerging out of the buried, unseen road structure, architectural elements mediating with urban stratification at the intersection of landscape, infrastructure and mobility.
