Special £350,000 bridges that were meant to beam bats opposite a bustling highway have been discharged as a ‘waste of money’ – after a animals usually abandoned them.

The 6 channel points were commissioned to stop bats being strike by trade as they changed between roosting and feeding sites.

The handle filigree and net gantries were ostensible to embrace a lines of hedgerows and trees that bats routinely follow with echolocation, heading them safely across a vital highway after a nine-mile widen was recently dualled.

But a investigate by a heading educational has found many of a mammals are channel during a tallness of about 15ft instead of a 25ft formerly – putting them right in a trail of lorries and vans that rumble past.

Professor John Altringham, of a expertise of biological sciences during Leeds University, pronounced a Highways England plan on a A11 between Barton Mills in Suffolk and Thetford in Norfolk had been a ‘waste of open money’.

‘They don’t do all of a ecological mandate of a bat,’ he said. 

‘The bats wish a hedgerow or a tree line to fly along and that provides them with preserve from a wind, insurance from predators and provides them with food and it’s a really large and really apparent structure for them to collect up.

At risk: But a new investigate has found many of a mammals are now channel during a tallness of about 15ft – putting them right in a trail of lorries and vans that rumble past. Above, one of a bridges circuitously Thetford, Norfolk

‘A handle overpass doesn’t benefaction any of those things to a bat so there is no good reason because a bat would compensate any courtesy to it and that’s what we find – they don’t.

‘There might have been lots of bats channel during these points in a past though not now. Those that do cranky fly too tighten to a ground.’

Professor Altringham also pronounced there were gaps where a existent corridors of trees finish and a bridges begin.

A improved resolution would have been a ‘green’ choice regulating existent foliage stretched on wires opposite a road, he added.

Local consultant John Goldsmith, who has been a member of a Norfolk Bat Group for 50 years, reliable there were about a dozen class in circuitously Thetford Forest.

‘When a highway was a singular carriageway some of a tree tops [bordered] tools of a highway and bats used these points to navigate,’ he said.

‘The new highway cuts a far-reaching tie by a timberland and these bridges were designed to keep bats above a turn of traffic.

‘We felt a handle structures would not surrogate for a former tree cover and a bats’ routes between their roosting and feeding sites would be disrupted.’

Mr Goldsmith also complained a ‘green bridge’ would have been some-more suitable, though added: ‘I’m certain this was a cost-saving practice as immature bridges are really expensive.’

Highways England, however, shielded a bridges. 

A orator said: ‘The measures on a A11 were mutated from prior designs… and were partial of a incomparable package, including a landscaping programme and synthetic bat roosts, dictated to support internal bat populations.’

The dualled track joining Norfolk and Suffolk was finished during a cost of £134 million in Dec final year.

The thought was initial suggested in a 1970s, though saw usually waste improvements until a bloc supervision concluded in 2010 to enhance a final singular carriageway section.
