New City Bypass Road Takes Shape in No Tonne at all

A 450-tonne crane is playing a critical role in helping to build a brand new bridge which will soon run under the A720 Edinburgh City Bypass to make way for the Borders Railway project.

Work to the bridge started in earnest in October with a 450-tonne crane hoisting forty-eight 22 tonne walls into place, along with twenty-four 66 tonne roof panels.

Ahead of works starting, a temporary dual carriageway opened alongside the A720 in September to allow the Borders Railway project team to create the new bridge safely, and with minimal disruption to a busy road.

Hugh Wark, Project Director, Network Rail, said:  

“Since traffic transferred to the temporary carriageway in September, the project team has achieved a huge amount of progress, from removing the original carriageway and embankment, to hoisting the new bridge structure into place.

“Once the bridge structure is secured, the team will then move onto waterproofing and backfilling the bridge ahead of preparing for the reinstatement of the original carriageway alignment.”

While work to the new bridge is underway, a 40mph speed limit will be in place over the length of the temporary carriageway for the safety of road users. The temporary carriageway is expected to be removed in spring 2014, when bridge work under the bypass is completed.
