Bats
House of Lords
Lord Marlesford (Conservative)
To ask Her Majesty's Government what was the location and cost of each of the bat bridges completed in England and Wales in the past five years; and what studies have been made of the cost-effectiveness of each bridge.
Earl Attlee (Whip, House of Lords; Conservative)
The table below provides details regarding which roads the Highways Agency has provided bat mitigation on during the past five years, the number of mitigation measures applied, and the respective cost.
| Scheme | No | Total Cost | Status |
| A38 Dobwalls Bypass | 2 | £300,000 | Constructed |
| A590 High and Low Newton Bypass | 1 | £84,000 | Constructed |
| A69 Haydon Bypass | 1 | £60,000 | Constructed |
| A595 Parton to Lillyhall Improvement | 1 | £34,000 | Constructed |
All elements of a scheme are subject to appraisal in line with published guidance and to specific value management requirements throughout the project lifecycle. A review is undertaken of the costs, benefits and other predicted impacts (including environmental) at key stages, to ensure benefits are optimised and costs challenged. Comparisons are also made with other projects so that decisions take account of the best available evidence. Consideration is also given to this at the end of projects so that lessons learnt can be applied in the future.
The Highways Agency has published a report titled A Review of Bat Mitigation in Relation to Highway Severance. The report is available on the Highways Agency website.
There is no central list of information relating to bat mitigation on local authority roads.
The Government do not hold information on the cost, location and cost-effectiveness of bat mitigation in Wales as this is a devolved matter and the responsibility of the Welsh Assembly Government.
