The motorway leaves the metropolitan area of Porto, through the urban areas of Ermesinde, Valongo, Paredes, Penafiel, until arriving at the mountainous town of Amarante.
It is also known as one of the most dangerous motorways in the country, particularly the descent from Campo to Valongo. Many improvements are being projected by the government in this respect.

Currently the highway has been extended into Bragança and the border with Spain, which opened in 2013. from through the Serra do Marão. The extension will also include a bridge reaching a height above ground of 230 metres (750 feet). Once extended the A4 will become Portugal's third-longest motorway, with a length of 223 km (139 mi).

Marão tunnel

On 7 May 2016, the Marão Tunnel was opened to traffic. The Túnel do Marão is Portugal's longest road tunnel, 5.6 km (3.5 mi) long.
