The viaduct over the Via Langhirano traffic circle, part of a road link in Parma, posed a technical challenge because of its design complexity and high traffic volume. Built in three phases, it includes a cable-stayed bridge and innovative works for safety and environmental sustainability.

Work on the widening of the A3 Naples-Pompeii-Salerno freeway, financed by ANAS and contracted out by the Società Autostrade Meridionali, involved the addition of the third lane, the upgrading of the Scafati and Castellammare interchanges, and the creation of new traffic circles to improve traffic flow. Archaeological and environmental interventions, such as the protection of century-old pine trees and the recovery of artifacts, characterized the project, which also included urgent adjustments for Pope John Paul II's visit to Pompeii.

The RAICAL/COGER grouping built a Commercial Park in Marcianise (CE) with related infrastructure, including internal roads, parking lots, and road connections. The main interventions included earthworks, sewer and drainage networks, construction of a highway overpass and underpass on the A1 Naples-Rome highway, and new interchanges to improve connections with S.S. 87 and S.P. 335, speeding up mobility between the Park and neighboring towns.
