The GC-3, known officially as Circunvalación de Las Palmas de Gran Canaria (Las Palmas de Gran Canaria Bypass) is a superhighway in Gran Canaria (Canary Islands). It connects the two trunk roads GC-1 (Autopista del Sur de Gran Canaria) and GC-2 (Autovía del Norte de Gran Canaria) over a length of 13 km (8.1 mi). A good half of the north-south traffic on the island is now handled by the GC-3, which significantly relieves the Avenida Marítima and the Túnel del Ingeniero Julio Luengo.
More than half of the 13 km (8.1 mi) long route leads over bridges or through tunnels. As a result, the total cost of the motorway was 228 million euros, most of which was raised by the European "FEDER" fund.
Construction began in 1997 and can be divided into five phases:
The maximum height difference on the route is 300 metres (980 ft) (lowest point at 30 m, highest point at 330 m).
