Motorways are the vital pulse of modern roads, linking cities, facilitating movement and bringing people together. These wide ribbons of tarmac are not just routes of travel, but true arteries through which economic activity and socio-cultural exchange flow.

With the rapid development of technology and the increase in the car fleet, motorways have become invisible threads linking geographically distant points. They are transport arteries facilitating the instantaneous movement of people and goods. They play a key role in infrastructure development and contribute to sustainable economic growth.

Motorway travel is not just a journey from one point to another; it is a journey through diverse landscapes where mountains change from fields and cities become metropolises. Along the motorways are landscapes that offer unique visual experiences and opportunities for discovery.

At night, motorways come alive with the light of headlights, creating a visual symphony. They are endless ribbons of light, leading to uncharted horizons and reminding travellers of the endless possibilities before them.

However, motorways are not just routes for cars. They become places of meeting and social interaction. Service stations, restaurants and rest areas create a sense of community where travellers can share their impressions and experiences.

These roads also bear the responsibility for the safety and comfort of travellers. Technology such as intelligent traffic management systems and driver assistance systems have made travelling more predictable and safer.

Thus, motorways are not only engineering structures but also a symbol of convergence and freedom. They reflect humanity’s desire to unite, to create bridges between different points on the map and, ultimately, between people.

Welcome to The Expressway Site, your premier source of information about “motorways” in the United States and Canada. In this blog, we will tell you what these roads are really like and why they are different from the usual motorways.

Difference between Expressways and Motorways:
Let many people think that motorways and motorways are the same thing, but there are actually differences. As defined by the U.S. Federal Highway Administration, motorways are the middle ground between a regular road and a fully controlled motorway.

Partial Access Control:
An important aspect of motorways is partial access control, defined by the use of police powers to restrict access to the road from adjacent property. This effectively restricts access and allows for smoother traffic flow.

Efficiency and Convenience:
Motorways provide a balance between traffic efficiency and convenience. Here you can find intersections at different levels and even traffic lights, but still maintain a clear limit on the number of carriageways. This creates optimal conditions for safe and fast travel.

Official FHWA Definition:
The US Federal Highway Administration officially defines motorways as roads with “partial access control”. This implies the use of enforcement agencies to control access to the road and strictly limit entry and exit points.

Interchanges and Minimum Intersections:
Although interchanges may be encountered, motorways seek to minimise direct approaches to private roads. This helps maintain high traffic volumes and reduces the risk of accidents.

In the following articles, we will delve deeper into the world of motorways, describing their characteristics, design and impact on transport infrastructure. Stay tuned to learn more about how these roads are shaping the future of roadways in North America.
