Vielha Tunnel (Juan Carlos I)
ES · N-230 · 5.2 km
What this restriction means
This tunnel has no ADR category. The country has not assigned one — dangerous-goods traffic is governed by a national restriction regime instead.
A national restriction regime applies here. Its scope, hours and conditions follow the national decision, not the A–E scale of ADR 1.9.5, so no category letter can be quoted for this tunnel. Please check the source below before planning a route.
Spain does not assign ADR tunnel categories (its 1.9.5 notification is empty). Tunnel regimes are set by resolutions of the DGT, the autonomous communities or municipalities — the exact scope and hours are given in the source below.

Restrictions & provenance
Time-restricted
Catalonia-wide ADR calendar bans (ISP/300/2026): Sundays and public holidays 08:00–24:00; eves of holidays (Wed/Thu) 16:00–24:00; consecutive-holiday pattern. During restriction days the Annex C goods exemptions apply at the Vielha tunnel only 06:00–10:00.
Dangerous-goods vehicles do not use the Juan Carlos I tube: since 07.08.2017 the ministry routes them through the parallel old Vielha tunnel (Alfonso XIII, 5260 m) as regulated passage controlled from the tunnel control centre (transportes.gob.es press note). Resolución ISP/300/2026 (BOE-A-2026-6095) additionally bans freight over 7,5 t on the access N-230 PK 116–187 in seasonal windows. No ADR tunnel category assigned.
