M1 BRIDGE LIFT HAILED A SUCCESS

September 22, 2009

We successfully lifted a new bridge into position across the M1 in the East Midlands over the weekend of September 19.

A five-mile stretch of the motorway was closed during the overnight operation which began on Saturday and is part of a project to widen a 14 mile stretch of the road between Junctions 25 and 28.

A 500-tonne crane was set up on the northbound carriageway to lift two girders weighing 57 tonnes into position while a smaller 250-tonne crane on the southbound carriageway lifted a second pair weighing 41 tonnes.

The bridge replaces a 42-year-old structure used to carry farm vehicles between Knowle Park Farm and a field on the opposite side of the motorway. The original bridge was not long enough to span the widened motorway and was demolished in January to make way for its 67.5m long replacement.

During the weekend’s road closure, which was timed to coincide with the quietest time on the motorway, gantry construction and surfacing work was also carried out.

Paul Tully from the Highways Agency said: “A total closure of the motorway is a rare occurrence and a major undertaking. We have to get things right and have to make sure the road can be reopened in good time. From our point of view things went very well.”

We are working on the widening project as part of MVM, a joint venture with Vinci Construction Grands Projets, Morgan Est and our consultants Gifford and WSP.

Work began in October 2007 and is expected to take three years.
