The 176 pages of road maps cover Britain at 3 miles to 1 inch (Western Isles, Orkney and Shetland at 4.75 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 includes the unique Philip's MapEasyTM place markers, which clip on and pull off to indicate different atlas pages along a route.Across the Channel, a full-page map shows Calais and Boulogne, and a double-page map shows the full extent of the northern French coast including all ferry ports.The atlas also includes route-planning maps, M25 and M60 maps, full listings of mobile speed-camera sites, distance table, 12 large-scale city approach maps with named arterial roads, and 55 extra-detailed town and city plans, airport plans and port plans.
