would be surprised
160 years of operation without major reconstruction would certainly surprise even the Italian architect of the viaduct, who was charged with a task to construct the entire railway line from Vienna to Prague and Děčín. In addition to an improvement of the technical condition of the bridge, a space for cultural and social events will be created in the future.
|Investor:||Railway Infrastructure Administration, state-owned company|
|Contractor:||HOCHTIEF CZ a. s., Division Traffic Infrastructure – leader of joint-venture “Negrelliho viadukt” (HOCHTIEF CZ, a. s., STRABAG Rail a. s., Avers, spol. s r.o.)|
|Project type:||Traffic infrastructure|
If it were not for the Charles Bridge, the Negrelli’s Viaduct would be the oldest bridge in Prague. It has one primacy nonetheless – it is the first Prague railway bridge across the Vltava River.
In 1845–1849, up to 3,000 Czech, German and Italian workers participated in its construction. Alois Negrelli himself, who was assigned to build a railway from Vienna to Prague and to Děčín came from South Tyrol.
The 1,120 m long viaduct had no competitor in Europe for more than fifty years. It consists of 87 arches, 77 of which are of sandstone and 8 of granite (over the river). Open without any restrictions, it survived the floods in 1865, 1890 and 2002. That was because it had been designed based on fresh experience with a flood in 1845.
In 1873, “Karlín Connecting Viaduct” was completed. It is 351 m long and consists of 26 arches – 10 of stone and 16 of brick. It connects Bubny with Libeň without the necessity of going to the Masaryk Railway Station.
That is the historical and cultural importance of this construction, on which a JV of the companies Hochtief, Strabag and Avers will carry out this project.
The bridge has been open for more than 160 years without any major reconstruction works. The reason for the current one is the fact that the bridge structure is in a critical condition, the superstructure is no longer meeting the standards and the signalling and security systems, power cables and overhead lines are obsolete.
The reconstruction will bring
This project is also part of the project under preparation – “Upgrade of Railway Line Prague–Kladno” including a branch line to the Václav Havel Airport.
