The A1 motorway, which connects Lisbon to Porto, was fully completed 35 years ago, on September 13, 1991. The continuous connection between Portugal's two largest cities was made possible with the opening of the section between Torres Novas and Condeixa-a-Nova, which marked the completion of this road infrastructure.
The A1 is one of the country's main motorways, serving as a fundamental road axis between the north and south of Portugal. Its opening represented an important milestone in the Portuguese transport network, facilitating circulation between the two main cities of the country.
Currently, the motorway records an average daily traffic exceeding 42,000 vehicles, highlighting its importance as an essential communication route. This volume of traffic demonstrates the vital role that the A1 continues to play in Portugal's road connectivity.
