On Monday morning a five kilometre tailback built up on the French side at Bardonnex, with around 45 minutes wait time, reported Swiss media including Le Matin.
“Monday is a big day in any case but normally we have a build up of 2.5 kilometres,” Yannick Przymusinski of the Saint-Julien-en-Genevois customs division told the paper.
Speaking to 20 Minutes, Michel Bachar, spokesman for Swiss border guards, said that travellers were understanding of the situation.
“Everything is going well. People are tolerant. Clearly the message that border controls will be increased has got through. For the moment there haven't been any incidents.”
“As for this evening, there's a risk things could get heated,” he warned.
People should be aware that a driving licence alone is no longer sufficient proof of identity for crossing the border, warns le Matin.

Despite the increased controls at major crossing points, several points along Switzerland's 100km border with France remain unmanned, reported Le Tribune de Genève.
Customs points including Croix-de-Rozon and Landecy were letting vehicles pass freely, said the paper, though traffic was heavier than normal, perhaps due to the tailbacks at other points.
“You can go into France and come back normally. But all the customs points in the canton are subject to particular vigilance,” Olivier Botteron of the Swiss border guards, told the Tribune.
