§ Mr. Ian Lloyd
asked the Minister of Transport what information he has on the cost of providing pedestrian subways or footbridges under or over three, four and six-lane carriageways, and on how these costs compare with those of similar facilities in other countries in Europe and the Commonwealth.
§ Mr. Tom Fraser
The cost of providing a pedestrian subway or footbridge may vary widely according to conditions at the particular site. The width of the road is only one of the factors affecting the cost. Other factors include the cost of land for staircases and ramps, and, for subways, the extent to which public utility services may need to be diverted. The cost of a subway is normally in the range of £25,000 to £75,000, and of a footbridge £5,000 to £20,000. No information about costs in other countries is readily available, but they are likely to show a similar variation.
