During the works, high‑complexity activities were managed such as the search and relocation of interfering utilities, hydraulic adjustments at interchanges (including Castellammare di Stabia), and the upgrade of accessibility and safety works: roundabouts, restoration of pipelines, and strengthening of lighting at the Scafati toll booth. In parallel, the intervention required attention to context: management of archaeological findings with the Superintendency and protection of centuries‑old Mediterranean pines in the affected areas.
