A4 motorway (Portugal)

The A 4 is a Portuguese motorway with a length of 63 kilometres (39 miles), running from Matosinhos to Amarante, where it narrows to become an IP road, signed as IP4 . 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.
