A5 motorway (Portugal)

The A5 is a 25-kilometre-long (16 mi) motorway, located in the Lisbon metropolitan area, Portugal.

[1] It connects Lisbon with Cascais.

The motorway is also known as Estoril Coast Motorway and it overlaps the Complementary Itinerary 15 (IC15).

The first section of the highway – connecting the Duarte Pacheco Viaduct in the City of Lisbon with the National Stadium in the Oeiras Municipality – was opened in 1944, becoming the first motorway in Portugal and one of the first in the world.

From 1945 to the early 1980s, it was officially designated National Road 7 (N7), when it became the A5.
