Video | 200t beams lifted onto M8 bridge

M8 beams

Construction has started on the largest single span bridge on Scotland’s £500M M8 project.

North Calder Water beam lift.

Transport Scotland has released time lapse footage of installation which shows nine pairs of 3m high steel beams, approximately 77m in length and weighing almost 2,000t, being lowered into position over the North Calder Water in North Lanarkshire.

The new bridge will carry three lanes in each direction and link the M8 to the A725. It is part of the motorway improvement programme for the M8, M73 and M74. The bridge construction is led by a Ferrovial Lagan joint venture.

In order to facilitate the lifting, a massive 90m high, 1,350t crane – the largest crawler crane in the UK and one of the biggest in Europe – was delivered to site by a fleet of 33 heavy goods vehicles.

Ferrovial Lagan construction manager Dario Saavedra said: “This is a significant milestone for the project and a successful operation which we are very proud of. The beam installation took nine days to complete, lifting the giant beams onto the two new bridge abutments, each of which contain over 6,000t of reinforced concrete.

“The beam lift was a complex piece of engineering and an important step towards completion of this impressive project.”
