The main objective of the project “D1 Bratislava – Triblavina, bridge D1/D4” is to build a bridge on the existing D1 motorway and to enable the concessionaire D4R7 to build the D4 motorway under the D1 motorway. The D1 motorway is on the section between Bratislava and Trnava, where there is also a designed bridge, originally 4-string, temporarily capacitated by adding another lane in each direction, at the expense of a paved side of the road. The aim of the project is to extend the D1 motorway, including the replacement of road construction in the Bratislava section – the Triblavina intersection and to ensure the transport connection between the motorways D1 and D4, through the implementation of the bridge SO 232-05 in the intersection of Ivanka North in km 1,713.
