Gospel Oak to Barking Underbridges Replacement

The project involved the replacement of four bridges on the Gospel Oak to Barking railway line over three weekends, during 50hr possessions of the railway to replace the 120 year old bridges.

All four of the bridges are located over narrow residential streets, which meant carefully planning on the size of the equipment and how it could be used. A 500 tonne crane was utilised for each bridge in very specific positions to ensure the work could be carried out without risking damage to the surrounding environment.

The existing bridge decks were removed in three sections, using the crane to remove one part at a time. The replacement bridge was fabricated and delivered in two sections; these were lifted into position such that the holding-down bolts for the bearings aligned with pre-formed sockets in the bearing plinths.
