Weekend closures at Hardengreen roundabout - Second phase of Borders Railway bridge installation works

The second phase of bridge installation works for Borders Railway will take place at Hardengreen roundabout this weekend. This follows the successful completion of the first phase of works which saw the concrete bridge beams lifted into place earlier this month.

This weekend of works will see the construction team complete the installation of the bridge deck. Works will start from 10pm on Friday 28th February until 6am on Monday 3rd March. During this time motorists are reminded that this will require the closure of Hardengreen roundabout, the A7 and local roads to allow this specialist engineering task to be carried out.

The construction of the new structure at Hardengreen roundabout is the longest new bridge to be built from scratch for the new railway line and therefore marks one of the project’s most significant construction milestones to date.

During phase one of works, which took place across the 14th – 17th February, a 30-strong construction team worked around the clock over the weekend to carry out the precise process of lifting the bridge’s four 107 tonne beams into place with a 1,200 tonne crane. Sections of the bridge deck and parapets were also installed. Once completed, the new bridge will span 71.5 metres.

Hugh Wark, project director, Network Rail, said: “Phase one of works saw the team carry out the most technically challenging part of the installation process. We even had one of the country’s biggest cranes onsite to help us lift the bridge’s very heavy beams into place. Luckily, good weather conditions meant that we could successfully complete this part of the works and move onto the next phase of activity as planned this weekend.

“While works are underway this weekend, the same closures, diversions and restrictions will be in place as were in the first phase. We encourage the travelling public to plan their journeys in advance whenever possible and apologise for the inconvenience while we carry out these works.”

BAM project director, Nissar Mohammed, commented: “We were very pleased with the progress made during phase one of the works and we look forward to completing the installation of one of the major structures on the route.

“Phase two of the works will see the team fully complete the installation of the bridge deck to allow the detailed design work of the bridge to be carried out without any further major road closures.”

The local diversions that will be in place during these works are:

  • Motorists coming to and from the Edinburgh City By-Pass, A720 are advised to use the A68 instead of the A7
  • HGVs travelling north and south should use the A68 rather than the A7
  • Midlothian motorists travelling north on the A7 should follow diversion signs for B704 along Cockpen Road
  • Motorists travelling towards Edinburgh from Newtongrange will be diverted along the B6482
  • Motorists using the B6392 (Dalhousie Rd) and B703 ( Newbattle Rd) are asked to follow the local diversion via A6094 (Eskbank Road) or B6392 (Melville Rd)
  • Only local access will be permitted on A7, South of Hardengreen -Roundabout to Dalhousie Mains cottages and local businesses.

Parking restrictions will also be in place for the duration of the weekend closures to allow for the moving of materials on the A6094 across Bonnyrigg Road, Eskbank Road and Lothian Street and along the B704 across Dundas Street and Cockpen Road.

As a result of the road closures around the perimeter of the works and in the interest of health and safety, members of the public will not be able to watch the works but are encouraged to keep up to date with progress via the project’s Twitter feed (@BordersRailway).

The planned works are weather dependent. Please ensure you check the Borders Railway website and Twitter page for up to date details: www.bordersrailway.co.uk / @BordersRailway
