Built in 1972 of steel construction with a precast concrete plank deck overlaid with a lightly reinforced concrete layer, consisting of two almost identical spans each 24.38m long. An assessment of the capacity of the footbridge carried out by Network Rail identified that the footbridge was not capable of carrying the loading required under current standards.
The main work items comprised replacement of the existing concrete plank deck with a GRP panel deck, upgrading of the deck support steelwork and total repainting of the remaining bridge steelwork.
Challenges addressed in carrying out these works included managing a suitable diversionary route for pedestrians, and carrying out all works in a series of 6 No. consecutive 24 hour possessions of the railway. Further challenges were presented due to the time of year scheduled for delivery, with winter conditions presenting further constraints on paint application techniques.
- 3.2 tonnes of new steelwork was installed to strengthen the deck and piers.
- Existing concrete deck was removed and replaced with 97 sq.m of new GRP deck.
- 525 sq.m of steelwork prepared and repainted with a new 3 coat moisture cured paint system.
- Various concrete repairs undertaken to piers and steps.
- New GRP coping units applied to span over railway.
