asked Her Majesty’s Government:
In respect of each local authority road scheme under construction or with full approval, what is (a) the estimated cost at full approval stage; (b) the benefit to cost ratio at full approval stage; (c) the current estimated gross cost of completion; and (d) the benefit to cost ratio using the current estimated gross cost of completion. [HL4742]
Information on (a) and (c) is available in a table which has recently been published on the Department for Transport's website at the following weblink at: www.dft.gov.uk/pgr/regional/ltp/major/majorscheme.pdf.
On (b), the following table lists the benefit to cost ratios (BCR) of the local authority road schemes that are either under construction or at full approval stage. The schemes were appraised in different years and due to changes in the Government’s appraisal methodology during this period, the BCRs reported have not all been calculated on the same basis, so they are not directly comparable between schemes.
