HS2 begins construction of the UK’s longest rail viaduct

Last week HS2, a high-speed rail company in the UK, began construction on the country’s longest rail viaduct. A team of workers lowered the first of nearly 300 piles that will serve as the foundation for the construction. Its total length will be 3.4 km, informs railway magazine Railway Supply with reference to the HS2 media center.

The viaduct will cross a series of lakes and rivers on the northwest edge of London at an altitude of about 10 meters and will be almost a kilometer longer than the bridge over the Firth of Forth on the east coast of Scotland.

Egypt signed an agreement with Siemens to build a high-speed rail network

On the new bridge trains will travel at speeds of up to 200 mph (320 km/h).

The structure will be supported by 56 pillars. Main contractor HS2 Ltd Align JV will build 292 piles during the year. Some of them will go underground to a depth of 55 meters.
