HS2 Phase 2b Select Committee: Crewe to Manchester - Understanding the Ground Risk across the Cheshire Plain
This report from HS2 Ltd reviews the ground conditions, the associated risks, and the mitigation measures for the Phase 2b Proposed Scheme.
The Phase 2b Crewe to Manchester Proposed Scheme passes across the Cheshire Plain in areas of former salt mining and other areas where salt mining is ongoing. The report addresses geological concerns in this area and sets out:
• HS2 Ltd’s understanding and interpretation of the existing ground conditions;
• How the route alignment and developed design has taken account of those ground conditions; and
• How HS2 Ltd plans to gather further information, develop the design, construct, and operate the Proposed Scheme.
The report may be used by petitioners during the Phase 2b Select Committee when hearing evidence on the ground conditions across the Cheshire Plain.
