The Danube Bridge linking Rousse and Giurgiu will be closed for technical tests for periods of up to six hours between October 21 and 23 2016, the Romanian National Company of Motorways and National Roads has told Bulgaria’s Road Infrastructure Agency.
The Road Infrastructure Agency said in a notice on its website that during that time, traffic on the bridge will be discontinued.
The checks follow a renovation of the bridge that has taken more than a year.
The closure to traffic is expected to cause long queues of lorries and cars.
Bulgarian media said that transport firms had been advised to redirect their lorries via the ferry at Silistra.
Media reports noted it was not clear what residents of Rousse, who regularly use the airport at Bucharest and who have already bought tickets, would do.
There is a second Danube Bridge, linking the Bulgarian city of Vidin to Romania’s Calafat. It is more than 350km from Rousse, with a driving time of more than four hours.
