5 November 2026 at 14:22

> Madrid City Council will shut the A-5 and M-30 link from 10 November to 23 December to install 128 beams and complete tunnel covering.

The connection between the **A-5 highway** and the **M-30 tunnel** will be completely closed in both directions from 10 November to 23 December. **Madrid City Council** is undertaking the 43-day closure to install 128 beams and cover the final 172 metres of the tunnel.

Surface traffic will be restricted to two lanes in each direction while 80,000 daily vehicles are diverted. Authorities recommend using the M-40 for long-distance travel, with the A-42, A-6, M-500, and M-503 serving as alternative corridors into the city.

A mobility plan will reinforce **EMT** bus lines by up to 25%, alongside increased services on Metro lines 3 and 10 and the C-5 **Cercanías**. Free special bus lines SE2 and SE3 remain operational, while new traffic lights will be installed at key local junctions.
