A sliding operation began last night to install a new steel bridge that will carry trams over the main rail station in the English city of Nottingham.
The 1,100 tonne bridge, which is 104m long and 14.5m wide, is being built in two sections. The first half has been built on top of four temporary towers at a height designed to allow it to be launched over Queens Road into its final position over Nottingham Station.
The movement of the first section of the steel bridge, which will be known as Karlsruhe Friendship Bridge, marks a milestone in the Nottingham Express Transit (NET) project to extend the city’s tram lines to the south and south west of the city.
The installation involves using hydraulic jacks to slide the bridge in 2.6m cycles on five consecutive nights. The bridge is expected to move up to 13m per night.
Martin Carroll, NET phase two project director for Taylor Woodrow Alstom, said: “The team has worked hard to bring the bridge to its current stage which has involved innovative and complex temporary works. The support of our supply chain partners, Cleveland Bridge and Mammoet, has been key to delivery. There remains much work to do, but the entire project team is motivated by this significant milestone. When complete, the combined bridges will form a landmark structure and become symbolic of the transport system within Nottingham of which the extended tram network is part.”
Once the first half of the bridge is positioned, there will be room in the compound to construct the second half. The bridge section will then be joined together and pushed over the station later this year.
When complete, the station bridge will connect with two further bridges across roads.
