A footbridge is going to be disassembled as part of work to electrify the mainline railway.

This August, Network Rail commenced work to reconstruct Undy Halt footbridge, which requires replacement as part of their work to electrify the mainline.

To electrify the railway, Network Rail need to ensure that the tracks have sufficient clearance levels for overhead line equipment under existing bridges. As Undy Half footbridge is too low, it is set to be demolished and replaced with a new structure. The new footbridge will be redesigned and relocated slightly, with the overall footprint of the bridge moving approximately 5-10 metres to the west.

The new footbridge will be of steel construction, painted ‘holly green’ (matching the railway palisade fencing in the area) and will have solid side walls along the span for safety reasons.

In order to dismantle the bridge, the steel will be cut into sections. A crane will be sited nearby, and temporary traffic lights will be used to protect the workforce.

For safety reasons, a large part of the demolition work can only be undertaken when the trains aren’t running. As such, work will be carried out largely on Saturday nights this month.

Network Rail propose that the new footbridge will be completed in December this year.
