It is not possible to predict future spending on the non-motorised user crossing programme as most of the schemes are delivered as part of larger improvements. Investigations are scheduled over a number of years and not all will result in schemes being taken forward. In addition, all new highways schemes receive a non-motorised user audit and this may result in further schemes that are not currently identified in the programme. Highways Agency expenditure for the three years from 2008-09 will be determined in the spending review to be concluded later in the year.
