 25 de Abril Bridge and North Viaduct

We will be discussing the 25 de Abril Bridge, focusing only on this specific bridge because it follows particular laws and regulations. It is also known as the "Viaducto Norte," and everything we talk about will apply strictly to this bridge.

First, the 25 de Abril Bridge is classified similarly to a motorway, meaning the same rules apply. Not all vehicles are allowed on the bridge, and speed limits are the same as those on motorways. There are three lanes of traffic in each direction, and a physical barrier separating lanes is mandatory, just as it would be on a motorway. Additionally, the bridge features a reversible lane, meaning traffic in the leftmost lane can change direction depending on the time of day, with signals indicating which direction is allowed.

Now, let's discuss the specific restrictions on the 25 de Abril Bridge:

1. In the event of a breakdown or accident, drivers and passengers should not leave their vehicles. Unlike on other roads where you'd typically wear a reflective vest and place warning triangles, here it's safer to stay inside your car because the bridge is monitored 24/7. Emergency assistance will be sent to you promptly. There are only two exceptions to this rule: if there is a risk of fire or if your car is at risk of falling off the bridge. In these cases, you should exit the vehicle and wait safely behind it, using it as a shield.

2. Vehicles transporting hazardous materials are only allowed to cross the bridge between 2:00 AM and 5:00 AM. This regulation minimizes risks during times of high traffic, ensuring that any accidents involving dangerous materials happen when fewer vehicles are on the road.

3. Driving lessons are prohibited on the bridge. Due to the narrow lanes and heavy traffic, it is not safe and not legal for learner drivers to practice on the 25 de Abril Bridge.

4. Certain types of vehicles are not allowed in the leftmost lane. These include:

   • Light vehicles with trailers
   • Motorcycles
   • Heavy vehicles, whether carrying goods or passengers

   Unlike other motorways where only heavy vehicles are restricted from using the left lane, the 25 de Abril Bridge also restricts motorbikes and vehicles with trailers from using this lane.
