This colour publication covers Peterborough and its immediate environs on 21 map pages. It also includes an enlarged city centre map on pages 22 and 23. Grid squares are based on the National Grid, the values of which are shown in the margin. Cycleways and bus-only routes are a special feature. A number of subsidiary addresses have been included on the maps, but where there has been insufficient space, the entry is shown in the index in italics with the adjacent access road or street.
