Project Outline At Three Colts Lane a 500t crane was utilised to dismantle and rebuild an existing rail steel underbridge. Space constraints and a complex OLE layout on a curve dictated that the works were constructed without the removal of the OLE. High winds over the Christmas period also impacted delivery however a concerted effort over the final four days of the programme by the Murphy team and supply chain partners resulted in a right time hand back of a structure deferred from previous control periods due to engineering difficulty.
