The A3 is a motorway in northeast Switzerland, running diagonally from France toward the southeast border, and passing by Zürich on the way. The total length of the A3 motorway spans roughly 180 kilometres (110 mi), but parts of the road share sections of the A1 and A2 motorways. The A3 belongs to the Swiss motorway network. It starts at the border in Basel, where it connects to French motorway A35. From the Wiese Motorway Fork, the route is shared with the A2.
