Grade II listed railway viaduct
||Littleborough, near Rochdale
Designed by George Stephenson and completed in 1839, this historically significant viaduct is Grade II listed and carries railway lines over the busy A58 intersection at Littleborough.
- Due to long-term effects of normal wear and tear, compounded by a shallow depth of fill above, this seven span viaduct was showing a variety of structural faults.
- The principle arch had developed five longitudinal cracks creating a series of arches and further weakening the structure.
- Vehicle impact damage to the barrel and stonework voussoirs on the spandrel walls.
A number of solutions were considered by English Heritage, Network Rail and its framework contractor, Edmund Nuttall, but none could solve the technical problems without adversely affecting the appearance.
- A systematic bespoke approach using a combination of concealed Helibeam bed joint reinforcement and pinning, using grouted CemTies, to reinstate full structural integrity.
- Specialist masonry repairs to improve damaged stonework.
- Rail services totally unaffected.
- All works completed on schedule and to budget.
- Viaduct sympathetically restored both structurally and visually.
