Prague Ring Road - Chlumecká Street Overpass

The new bridges had replaced an obsolete overpass in the eastern part of the Czech capital.

The eastern part of the Prague Ring Road near the Černý Most district is one of the busiest in Prague with up to 50,000 cars passing through daily. This section, which was built in the 1980s is in a poor technical condition. So is the overpass over the Chlumecká street, a twin bridge made of precast concrete girders on the ring road, going over the road connecting districts Černý Most and Horní Počernice. It was built thirty years ago as a part of the R1 Satalice-Běchovice road and put into operation at the end of 1984. It has not undergone any major refurbishment since then.

Even though the name of the contract (in Czech) refers to "just" a repair of the overpass, the scope of works is actually more extensive - it involves the demolition of the existing bridges on the Prague Ring Road (including the substructure), which will be replaced with two new bridge structures. The works were divided into two phases. In the first one, the construction companies had first demolished the original bridge going towards the centre of Prague, built foundations for bridge abutments and pillars, installed pre-stressed precast concrete girders and executed a cast-in-place RC bridge deck, which is contrasting with the roadway due to its bright white colour. A new asphalt pavement with temporary road markings was laid on the bridge deck, to enable opening of the western part of the bridge structure to traffic. And since the original bridge structure was also a twin bridge, the second phase of the project shall be carried out in a similar way.
