Underground structures central to £9.5M Devon rail flood defence

Network Rail has said that work to construct a £9.5M flood defence scheme in Devon on the Exeter to Salisbury rail line has got underway this week.

Two 550t underground bridge structures made of culvert sections will be installed underneath the railway line at Axe Valley on sites at Axe Farm and Broom Lane.

The installation of these structures will reduce the likelihood of flooding from a one in five year risk, to a one in 20 year risk, based on Network Rail’s flood risk modelling.

The new culvert structure will significantly reduce flood risk

The line between Axminster and Crewkerne has been prone to flooding in recent years, causing significant delays and disruption to passengers.

The nine month long scheme will involve major earthworks with up to 9,000t of material being excavated to allow the new culvert structures to be installed.
