Tunneling in Pontefract was challenging due to the area's complex geology, which included layers of soft clay and hard rock, making excavation unpredictable and labor-intensive. Additionally, the presence of groundwater and historical mining activity posed risks of collapses and flooding, further complicating the tunneling process. These factors necessitated specialized engineering techniques and increased the overall cost and duration of tunneling projects.
