# Seminario Tunnel closure extended to April 2027 > Live situation record from CLSTR: https://clstr.news/situations/seminario-tunnel-closure-in-emiliaromagna > Updated: 2026-08-02T15:26:33.000Z. Sources: 16. Developments: 3. After an initial political dispute over the safety of the Galleria del Seminario tunnel, regional authorities, law‑enforcement and ANAS signed a convergence protocol in July 2026. The agreement assigned ANAS the upkeep of the detour, replacement of vertical and horizontal signage, installation of margin devices and provision of winter ice‑prevention and snow‑removal services. Municipalities will issue traffic ordinances, monitor flow and support road fluidity, while an emergency corridor for rescue vehicles can be activated on request. A joint inspection on 16 July 2026 confirmed that fire‑safety regulations require the extraordinary maintenance to start before the security devices expire on 7 August, precluding any postponement to September. Consequently, the tunnel will be closed for 270 days, from 7 August 2026 until 30 April 2027, with traffic diverted to a longer alternative route. The municipalities may shorten the detour once Carpineti finalises its plan. In early August, the nearby Monte Pergola tunnel reopened after five years of work, underscoring the broader push to upgrade Italy’s road infrastructure. Mayors of Carpineti and Castelnovo Monti reiterated the inconvenience for commuters and tourism but urged residents to endure the disruption while safety upgrades proceed. ## Claims - A meeting was held on 15 July at the Prefecture, chaired by Prefect Salvatore Angieri and attended by provincial and municipal officials and representatives of law‑enforcement and ANAS.
