The re-shaping of A2 provides an opportunity to introduce a more consistent visual aspect to this stretch of motorway. The main aim of the design is to work within a broad, urban architectural vision of integrality and coherence, whilst providing this important route with a recognizable identity. This identity is expressed through the efficiency in the design of the various elements by way of a simple concept which lends itself to repetition. The structural elements are durable and low-maintenance while the detailing is designed to withstand the effects of weathering and pollution. The concrete sound barriers are clad in a continuous relief, while the transparent barriers are printed with this same pattern; an abstracted migrating bird which alludes to the identity of the A2 as a section of the European route Amsterdam – Palermo.
