Prittlewell Footbridge Refurbishment

Prittlewell Railway Station is on the Shenfield to Southend Line, serving the residential district of Prittlewell in Southend-on-Sea, Essex, and lying just one mile north of the town centre. The station is a two-platform category E station with an open footbridge linking the two platforms. This section of the rail network is electrified with overhead lines. There are commercial and residential properties within 25m of the station.

The existing footbridge has been identified as being subject to extensive defects beyond reasonable repair, and a new footbridge is required to retain access between platforms. The existing footbridge is still currently open to the public and will be removed on installation of the new footbridge.

 

The existing footbridge has a single span lattice web girder deck, with a staircase at each end, supported on trestle towers. Luminaires are present to each top landing. Services are present across the running lines within cable containment trays fixed to the external faces of the structure.

Potential hazards:

  • Buried services

  • Contaminated land

  • All platform fill material to be regarded as contaminated.
