Barajas Tunnel (M-111)
ES · M-111 (PK 1,1–5,0) · 2.6 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.
