Motorists heading south for the summer holidays face delays of up to five hours on Europe's most direct north-south route. On Saturday, columns of traffic up to 20 kilometres long had built up on the two-lane motorway heading into Switzerland's Gotthard tunnel.
Frustrated holiday-makers making the journey south to Italy for the summer holidays were advised to avoid the A2 motorway through the tunnel by the Swiss Touring Club. On Saturday, traffic came to a halt between Erstfeld and Göschenen, both situated in Canton Uri.
It was a similar story at the Chiasso border crossing between Switzerland and Italy where frustrated motorists were stuck in a 7 kilometre long jam. The delay here was one hour.
The Club recommended that motorists use alternative routes through the St Bernard Pass or the Lötschberg.
