Hindhead Tunnel
The Hindhead Tunnel, opened in 2011, is part of the dual-carriageway Hindhead bypass that replaced one of the last remaining stretches of single-carriageway on the A3, the London to Portsmouth road.〔 The bypass was constructed to improve road safety, reduce congestion and improve air quality.〔(【引用サイトリンク】author=Mott MacDonald )〕 At in length, the tunnel is the longest non-estuarial road tunnel in the United Kingdom, and takes the road beneath the Devil's Punch Bowl, a Site of Special Scientific Interest.
==History==
A naval dockyard has existed in Portsmouth since at least Tudor times,〔(【引用サイトリンク】Welcome to Portsmouth Historic Dockyard )〕 giving significant importance to the road linking that city with London. The original route skirted the north-western limits of The Weald climbing to the summit of Gibbet Hill close to Hindhead. In 1826 the road, which in the 1920s was designated as the A3, was rebuilt around the Devil's Punch Bowl to ensure that the gradient was no more than 5%.〔(【引用サイトリンク】The Devil's Punch Bowl and the Hindhead Tunnel )〕
By the start of the new millennium most of the A3 had been dualled; of the route from Southfields to Havant, only the section that passed through Hindhead and the Devil's Punch Bowl was still single carriageway. This section, which passed through an Area of Outstanding Natural Beauty (AONB), operated at or above capacity for much of the day and had an accident rate 40% higher than the national average for that class of road.
