Section G is largely urban, but also includes a Site of Special Scientific Interest (SSSI). It spans Runnymede Borough Council and Spelthorne District Council.

Preferred route description

Section G is around 4km long and starts at the approach to the A320/M25 and, after a trenchless crossing of the A320/M25, it continues through Abbey Manor Golf Course with a further trenchless crossing of the Chertsey Branch railway line between Chertsey and Addlestone Stations.

It then crosses under the A317 using trenchless techniques, before passing through the playing fields at Addlestone Moor.

There are then two trenchless sub-options for the crossing of the River Thames, as the route diverts away from the existing pipeline to avoid Dumsey Meadow Site of Special Scientific Interest. Both options cross the River Thames and the B375 and meet after crossing the M3, where this section ends.

For more information about the sub-options please view our Consultation Brochure.
