Marston Box Rail Bridge

In November 2021, it was announced that the bridge would be installed using the box slide method to minimise disruption to the motorway.^[1]

The M42 was closed between junctions nine and ten from 24 December to 31 December 2021 for preparatory works.^[2]

In December 2022 the bridge deck was slid 165 metres (541 feet) into place over a period of forty hours.^[3] To allow the work to take place the southbound carriageway was closed on 23 December and the northbound carriageway was closed on 24 December. Both directions were reopened on 1 January 2023, two days ahead of schedule.^[4][5]
