Ardleigh Green Bridge

Electrification Case Study

Ardleigh Green Bridge (AGB) carries four lanes of the A127 Southend Arterial road across four lines of an overhead electrified, commuter railway line. REL was contracted to move and relocate the OLE wiring to allow for the demolition of old structures.

At the inception of this job, REL was contracted to drop all OLE wires relating to the mains lines (both roads) to ground level/the 4ft to allow protection (robust protection by others), and to relocate the OLE over both roads of the electrics to a permanent design location.

On further assessment of the job, REL proposed an alternative solution to complete the OLE works.
