Carnwadric Ltd was awarded civils package along with Exmouth’ type footbridge removal and the installation of the new tum 400 new steel superstructure, fabrication by others.
The footpath from Beach Road to Seaford Beach in Newhaven passes over the single line railway between Newhaven Harbour and Bishopstone stations on an ‘Exmouth’ type footbridge. This design of precast concrete bridge, a product of Exmouth Concrete Works, was widely used by the Southern Railway and Southern Region, from the early 1920s to late 1970s, but many have since been replaced as corroding reinforcement and spalling concrete weakened them.
Oyster Pond footbridge had been deteriorating for some years and, to maintain its integrity, had a temporary timber prop on the down line formation and the trestles had been encased in blockwork.
Network Rail approved the replacement of Oyster Pond footbridge with a standard steel structure.
The land available meant the layout was asymmetric, with a single flight on the Up side and a 180° cranked flight on the Down side. The new bridge is of twin track span to permit future doubling here and is located four metres west of the existing structure. This optimises the use of available land for the stair flights and also permitted the new foundations to be constructed prior to the demolition of the concrete structure.
All works were completed on programme and within budget..
Good relationship with local residents, kept informed throughout the project.
Good relationship with Local Authority Environmental Officer who was consulted and briefed at an early stage in the project cycle to discuss to mitigate against any negative impacts as a result of the construction works.
