Romsey Road Bridge Replacement (M27)

This scheme has involved replacement of the existing reinforced concrete bridge, over the M27 at Rownhams, in Hampshire.  Suttle Projects’ involvement, as second-tier supplier to Osborne’s Highways Division included the following elements:

• Enabling works to create a security point, a metaled site access extending to 200m.
• Construction of a site compound with associated drainage for a large two-storey modular project office.
• Construction of a launch area and haul route for a new bridge deck to be installed by high load capacity transporter, including reinforced concrete ramp slabs off the existing hard shoulder.
• Sheet piling to facilitate part of the temporary access road construction.
• Installation of piling for the new bridge structure, including 900mm diameter cased bored bearing piles.
• Anchor installation and reinforced earth banks, for soil retention around the piling platform and new abutments.

These works were thus let in two parts: earthworks & civils, and piling.  The piling was completed with a bored piling variant Casagrande B125 rig.
