Saltley Area N1/N2 Structures

The Saltley Area works encompass a diverse range of major civil engineering structures, including two multi-span road bridges constructed immediately adjacent to live rail infrastructure, a 450m water retaining structure managing overflow from the River Rea, a highly skewed bridge spanning a live canal, and a series of substantial slabs and retaining walls reaching heights of up to 13 m, all delivered within a constrained and operational urban environment.

As a long-term delivery partner to BBV on this section, MPB has been embedded from the outset. Following a three-month preconstruction phase supporting BBV with planning and sequencing of the initial assets, we are now fully integrated within the project team. Together, we are optimising construction methodology, access strategies, resource planning, and temporary works to drive efficiency, safety, and programme certainty across this critical part of the HS2 route.

CHALLENGES / SUCCESSES

  • Aston Church Road Overbridge substructures were accelerated to meet the possession requirements to install the structure with a 25% programme saving.
  • Saltley West Retaining walls were constructed at a height of 13m only 5m from the nearest live running line of the Network Rail infrastructure.
  • MPB have developed the construction strategy for Saltley Canal underbridge providing a tower crane (plus all temporary works and NR approvals) and will manage the construction of the steel / concrete composite bridge deck over the canal providing pontoons, craneage and installation teams.
  • Construction of the water retaining River Rea overflow structure which has complex geometry, a dished dry water channel and is constructed within a propped, sheet piled cofferdam.
