A3

Route

This is the former A3 at Hindhead

Main Article: A3 route

A road with some history and strategic significance, as it connects London with its principal naval port. In the times of the Napoleonic Wars, when the Straits of Dover were vulnerable, this road became London's principal link with the Channel ports. Its history has also given it more than its fair share of reputations for highwaymen.

From its creation in 1936, the London-Portsmouth trunk road followed the A3 throughout its length.

History

The A3 at Hook during the 1960s

Main Article: A3 history

The A3 like many roads was mainly S2 at Classification. Since then most of the road has been upgraded to dual carriageway. The section at Hindhead was the last trunk section of single carriageway outside TfL control, until replaced by the Hindhead Tunnel in 2011.

Main Article: Hindhead Tunnel

The Hindhead Bypass and Tunnel provide full grade-separation of all the roads between Thursley and the Hampshire border. Construction of the tunnel started in early 2007 and it opened on 27/07/2011 and 29/07/2011. The old route from Hindhead Crossroads to Bramshott Chase has been renumbered as the A333, while the northern section has been removed and is now a cycle path.

Future

Expressway proposals

In December 2017, it was proposed that the A3 could be upgraded to an expressway as part of the proposals to introduce a new type of road network. The proposal includes different expressway types with an aspiration that the highest quality expressways will be given motorway designation and an Ax(M) number.

1925	Cosham Northern Road	The 0.7 mile road to bypass the High Street was opened on 28 May 1925 by Frank J. Privett, Mayor of Portsmouth.
