Philip's Big Road Atlas Britain and Ireland 2013 contains 96 pages of road maps covering Britain at 3 miles to 1 inch (Scottish Highlands and Western Isles at 4 miles to 1 inch, Orkney and Shetland at 5.25 miles to 1 inch). 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 route-planning maps, a distance table, 12 large-scale city approach maps with named arterial roads, and 58 extra-detailed and fully indexed town and city plans.
