Tips for not getting lost on the M-30

not getting lost on the M30

Sometimes it can be difficult to find our way on the M-30. Driving on this road can be quite an adventure, especially if you’re not used to it. It’s the largest network of urban tunnels in Europe. But it has the disadvantage that your vehicle or mobile’s GPS may not always work. No matter how many years go by, there are still many drivers who get lost on this road. So before we get into it, it’s important to be familiar with the signs and signals, as well as your options for changing directions, so that you don’t get lost on the M-30.

Learn how to interpret the signs on the M-30

First of all, it’s important to understand the names that are commonly used for the different roads and the name with which they appear on the signs. For example, when we talk about the “Burgos motorway”, we’re talking about the A1, which appears as such on the signs. The A2 is the Barcelona motorway, the A3 the Valencia motorway, the indications to the A4 take us to the Andalusia motorway, the A5 corresponds to the Extremadura motorway, the A6 is the A Coruña motorway, and if you follow the indications from the A42, you’ll end up on the Toledo motorway.

It’s very important that you understand the equivalence between the name of the road and its code, since we won’t always find both (for example, A1 Burgos), and it’s most more likely that you’ll only find the code (A1).

You should also know that the M30 is not included in the European numbered itineraries.

On the signs on the M30, first you’ll find the M30 itself, followed by the first street or point of interest, and the first ring road with its number and destination (e.g. A-1 Burgos), followed by the numbers of the following rings roads which you can access (A2, A3…). The M607 “Carretera de Colmenar” is also included as a destination in the direction of the M30 itself, which doesn’t occur for the M11, M23 and M500, which are only included on the signs for their corresponding exits.

Remember that the signs on the main section appear in blue; those on the service roads are white; and on the streets within the city they appear in green. On the main section, you’ll find exit signs towards the service road, which you’ll have to pay attention to in order to not miss your destination.

How to change directions on the M30

On the M30 there are no signs that tell you how to change directions, a manoeuvre that is very necessary if you’ve missed your exit. If you’ve gone past your exit, you must get off the M30 and look for an alternative route to your destination.

Depending on the exit, we can get back on the M30 heading in the opposite direction and take our exit, or we will look for a route off of the M30. In this case, we can use our car or phone’s GPS without fear of interference, since we’re outside of the tunnel. Finally, there is the option of completing the full circle of the M30, which isn’t an ideal solution since it takes up a lot of time and fuel (the M30 loop is approximately 32 kilometres in total). Luckily, there are shortcuts like the bypass that allows us connect the eastern and western sectors, avoiding the south knot.

Tunnel signs on the M30

In addition to the conventional signs, the walls of the M30 tunnels are marked so that it’s easy to not get lost. Every 20 metres we’ll find an alphanumeric code that tells us the driver’s exact position, making it easy to find them in an emergency.

You’ll also find a lot of variable-message signs with priority indications on fixed signs, where you’ll find information about possible detours.

Points where you should pay attention

There are 3 points on the M30 where you should pay special attention:

  • Closure of the M30 northbound in Manoteras. At this point, if you continue straight you will connect with the A-1. To continue on the M30, you must take the M30 Avda. Ilustración exit.

  • Closure of the M30 eastbound in Manoteras. Remember to stay in the right lanes to continue on the M30, if you continue straight you’ll get on the M-11 towards the perderse en M-30
  • M-30 tunnels southbound, kilometre 15+800 (15XC80). Just after passing the exit towards Marqués de Vadillo y Pirámdes, the M30 splits into 2. The right lanes continue to follow the M30 normally, connecting with all exits (A42, A4, Méndez Álvaro, Vallecas, O’Donnell and C/ Alcalá). The left lanes lead to the bypass. This tunnel avoids all of these exits, and is the route we advise if you are heading towards the A3, A2 and A1.

Tips para no perderse en la M30 2

As you can see, driving on the M30 is the same as driving on other roads, with the main difference being that it’s within the city and there’s more traffic. In any case, by following the signs and interpreting them correctly, we will successfully reach our destination.
