Essential repair works to start in Alton

Friday, 20 June 2014

Essential repair works to a partially collapsed culvert on the B3006 near Selborne, Alton, is due to start on Monday June 23.

The existing east wall of the Norton Farm culvert has partially collapsed. A temporary propping system was installed to avoid further deterioration of the structure.

Culverts are drainage systems situated under embankments that transport storm water from one side to another to ensure effective drainage. They allow water to pass underneath roads, railways and structures.

Norton Farm Culvert is located east of the junction of Selborne Road (B3006) and Hall Lane.

The repairs will take around four weeks and will be carried out by contractor COLAS Ltd.

The existing culvert will be lengthened with a high density polyethylene pipe. It will be placed at the collapsed end and back filled with concrete and granular material to the top of the wall. A new brick wall will be built at the east end of the extended culvert and existing tubular railings will be replaced.

One lane (east) will be closed on Selborne Road and there will be 24 hour three way traffic signals on Selborne Road and Hall Lane. The footpath running at the top of north embankment will be closed for the works duration for safety reasons.

Councillor Seán Woodward, Hampshire County Council's Executive Member for Economy, Transport and Environment, said: "Whilst the culvert is only small there is a steep, partially collapsed embankment above it supporting the busy B3006 Selbourne Road. This embankment is currently propped up with scaffolding but this is not a long term solution and it is reasonable to expect further erosion as there remains an open pipe at the top of the slope. This is essential repair work, but we will do all we can to keep disruption to a minimum."
