"The opening of the bridge is a technical issue that will be solved soon," the statement said.
The bridge was to have been opened on Tuesday. Slovenia had protested over the construction of the bridge and the road leading to the town of Sveti Martin na Muri, saying that the bridge would change the situation on the border that had existed when the two countries gained independence 15 years ago.
Slovenia insists that the bridge would increase the risk of flooding in the Slovene town of Hotize and that it was built without the consent or cooperation of the Slovene government.
The Croatian Ministry of Foreign Affairs and European Integration dismissed the Slovene accusations, saying that it was beyond dispute the bridge was situated in Croatian territory and that the construction work had been done in consultation with all relevant Slovene authorities in accordance with the Agreement on Border Traffic and Cooperation.
