The start of Bulgaria's long weekend between May 1 - 6 has caused traffic jams on the road and border crossing to Greece as Bulgarians have decided to spend the long weekend in Greece, Focus news agency said.

At the Vladaya borough, Sofia's exit point for the highway to Greece, there was a 10 km traffic jam before 11am on May 1, Focus said.

At about that time there was a two km file at the Koulata border point with Greece, Focus said.

Bulgaria's government has announced May 1 to 6 as official non-working days, giving most of the country a long weekend off.  May 1 and May 6 are official holidays, Labour day and Gergyovden respectively, which in 2008 fall on a Thursday and Tuesday. Those who do not work on May 2 and 5, will have to work two Saturdays later in May.
