New HS2 bridge installed in just two days

M42 reopened ahead of schedule as new HS2 bridge installed in just two days

To ensure that the local road network is fit for purpose when the future HS2 Interchange Station is operational, HS2 contractors are expanding and improving the existing network and creating new routes on HS2 land.

On Friday 7 August 2020, junctions 6 and 7A (northbound) and junctions 7 and 6 (southbound) of the M42 were closed to traffic. This closure enabled early works contractor, LM, to safely install a 65 metre bridge over the motorway.

We’re pleased to inform you that the closure of the M42 has been lifted and road users can now travel in both directions. Work to install the 2,750 tonne, 65 metre long bridge, which spans the width of the M42, was completed in just two days and the motorway reopened to road users earlier than planned.

A 448-wheel transporter took just one hour and 45 minutes to move the bridge span 150 metres, where it was affixed to a composite concrete deck to complete the overall bridge structure. Traditional construction methods would have required several weeks of lane closures on both carriageways, followed by additional weekend and overnight closures.

The successful installation marks the completion of the first of four bridges to be built close to the new Interchange Station. It will form part of the major remodelling of the existing road network to improve the circulation of traffic around the HS2 railway line and the new Interchange Station.
