Prague – Reconstruction of the Negrelli viaduct in Prague is likely to be stretched. Builders will have to break and rebuild 14 bridge vaults because of the technical state, the status of the other two will still be evaluated. Today, the Railway Infrastructure Administration (SŽDC) presented the working process during a press conference. The repairs of the protected viaduct with a total of 1.4 billion crowns had to be completed in the autumn of 2019, according to the original assumptions.

According to Martin Ředina of the Hochtief Building Company, preparatory works have shown that some parts of the bridge are in a worse condition than originally assumed. The deadline for completing modernization is now estimated at April 2020, but the exact date is only known in the next correction procedure.

"Viaduct is a unique cultural monument, we adjust it sensitively according to the requirements of nature conservationists and at the same time to increase the comfort of the passengers on the railway," said Transportminister Dan Ťok (for YES).

Verwelok also welcomed the reconstruction of the viaduct with maximum use of original materials and the effort to maintain the monumental value. "Here, some pillars and arches will do all over again and they will do the same as 170 years ago," he told journalists during a tour of the building. "The bridge will basically look like what it looked like when it came out," he added.

According to the minister, the reconstruction of the Negrelli viaduct is the first building in the context of a new railway project in Kladno with a branch to the Václav Havel airport. Prague is preparing other railway constructions according to him. Reconstruction, for example, must pass the railway bridge over Výtoni to increase capacity.

Reconstruction is according to the rail administration in the third. Now the work would have to move to the riverside of the Vltava river between the riverside and Stvanica. Last year, SŽDC removed the installation and extensions and removed the track and the traction lines.

According to the railway men's plan, they are redeveloping all 99 original bridges. Two bridge constructions between the streets of the First Regiment and Křížík are completely replaced. At the same time, the reconstruction will unite all parts that had a different design or shape. In addition, the builders will completely replace the railway superstructure, including the technological parts and the restoration of the foundations. Reconstruction should reduce the noise of passing trains by recording anti-vibration mats.

According to Jiri Svoboda, general director of SŽDC, the reconstruction should enable the introduction of a line speed of 60 km / h. At the same time, smoothness and number of trains must be increased to 14 pairs per hour. The security and communication technology will also be new.

RIA also considers the use of space under safes for commercial and social use in the future. We are still working on these parts.

The Negrelli viaduct was commissioned in 1850. The reconstruction of the 1110 meter long viaduct started last summer and was compiled by Hochtief, Strabag and Avers. Viaduct is named after the builder Alois Negrelli.
