Borders Railway prepares for installation of longest new bridge

L

The £200m Borders Railway project in Scotland is preparing for one of its most significant construction milestones to date as the longest bridge to be built from scratch is installed at Hardengreen roundabout near Eskbank, just south of the Edinburgh Bypass.

The installation will see a 1200 tonne crane used to hoist the bridge’s four beams into place, each weighing 107 tonnes; the equivalent to around 55 cars. A 30-strong construction team will work around the clock during the road closures to install the bridge beams and create the new bridge deck.

The preparation works at Hardengreen Roundabout started in September 2013 saw the project’s main contractors, BAM, carry out extensive piling works and construction of bridge abutments.

Hugh Wark, project director, Network Rail, said: “The installation of this new bridge structure is a major construction milestone for the team. Not only will it transform the visual impact of the landscape and connect the railway from north to south but it is the longest bridge to be built from scratch along the new route.”
