THE Grade II listed Chippenham railway arches are undergoing major repairs as part of Network Rail’s Railway Upgrade Plan.

The viaduct, where New Road meets Marshfield Road, is one of the town’s best-known landmarks and has been partly fenced while work is underway.

A spokesman from Network Rail said: “The natural deterioration of the Bath stonework and original brick construction is such that some parts of the structure are crumbling, which in some instances has required the closure of adjacent roads and footpaths. These works will address those areas that are most in need of repair.”

The work, which will be finish in spring, includes the removal of vegetation, the replacement or repair of damaged bricks and Bath stone, and the repair of cracks through the structure.

The nine-arch viaduct, which has limestone on the north side and brick on the south, was built in 1841 to carry Brunel’s Great Western Railway over the town.
