Philip's Road Atlas Britain and Ireland 2012 contains 160 pages of road maps covering Britain at 3 miles to 1 inch, with the Western Isles, Orkney and Shetland at smaller scales. The maps clearly mark service areas, roundabouts and multi-level junctions, and in rural areas distinguish between roads over and under 4 metres wide - a boon for drivers of wide vehicles. The atlas also includes 10 pages of route-planning maps, a distance table, 4 large-scale city approach maps with named arterial roads, and 32 extra-detailed town and city plans.
