Bridges and grade-separated interchanges

Pružinka Bridge is a part of the Ladce – Sverepec section of the D1 motorway. The bridge was built on from the geological point of view an exceptionally demanding site. The entire bridge consists of only one reinforced concrete unit from cast-in-situ prestressed concrete. The unit is delimited only by two expansion joints. It is the longest expansion unit in the Slovak Republic. The bridge was built applying the technology that uses special travelling scaffolding that allowed construction of 4 m of bridge deck a day.

The D1 motorway contains nine bridges. The most dominant bridge is the one that spans over the valley of the Kopytovský brook and the III.class road leading to Lipovce, in immediate vicinity of the village of Fričovce. The bridge has a bearing structure from post-tensioned concrete. The height of the bridge above the terrain level is 28 m and its width arrangement corresponds with the width of the motorway. The bearing structure of the bridge consists of continuous single-cell box girders of a constant height. They were built by using the free cantilever concreting method.

The Mária Valéria bridge is situated at 1718,5 km of Danube river between the cities of Ostrihom and Štúrovo. The bridge spans consist of truss girders and lower bridge deck. The truss girder structure retains its original shape but made of new materials and bears the coupled reinforced concrete bridge deck. Layout-wise is represents a straight-line bridge with the carriageway in vertical curve. Besides the road pavement the bridge contains also a bicycle path and a pedestrian path. All the components of the bridge have been built maintaining the typical shapes of the original bridge.

The bridge is situated on I/68 road leading from Prešov through Stará Ľubovňa to Poprad in the urban area of the town of Stará Lubovňa. It spans over the Poprad river and connects the town centre with the traffic junction consisting of the railway station, bus station, and the the Podsadok town district. It concerned a reconstruction of an existing bridge. The bearing structure of the bridge was reinforced by prestressing steel – tendons. At the same time the sewerage pipes that had not been used any more were removed and the damaged layers of bitumen and water-proof material on the bridge deck were replaced by a coupling reinforced concrete slab, water-proofing, and modified AB surfacing.

Construction of a new bridge over the river in the village of Vysoká nad Uhom that is situated in the east of Slovakia, close to the borders with the Ukraine. The bearing structure of the bridge was built by use of the free cantilever concreting method as a concrete structure from prestressed concrete. The new bridge allows smooth and safe traffic for all - motor vehicles, bicycles, and pedestrians.

It concerns a reconstruction of the two lane bridge in the village of Podčičva that is situated not far from the town of Vranov nad Topľou. The reconstruction works involved the exchange of the road pavement, reinforcement of the bearing structure, and reconstruction works on a part of the adjacent junction. Parts of the bearing structure brackets were removed and the reinforcement was ensured through prestressing steel- tendons and a coupling slab.

Grade-separated interchange Prešovská – Sečovská is one of the most remarkable road constructions within the territory of the City of Košice. The interchange addresses crossing of two roads of international importance – I/68 and I/50. Two new bridges over the Hornád river are part of the construction. The bridges were built using the free cantilever concreting method and the bearing structure of variable single-cell box cross-section. The purpose of the construction project was to ensure smooth, safe, and fast traffic in Košice.

Road I/50 – Južné nábrežie is a part of the outer ringroad in Košice. The newly built four lane road is situated away from the built-up area which reduces its impact on the environment. The widths arrangement and grade-separated design of important interchanges interconnect with the already existing roads. The construction project includes also one prefabricated concrete bridge, one steel bridge over the Hornád river, and two cast-in situ bridges over the tram railway.
