Hertfordshire is a traditional county immediately to the north of London.

Geography & Economy

Letchworth Garden City

Hertfordshire heads north from the edge of London; indeed part of the Greater London conurbation lies within the county, which extends some distance inside the M25. Much of Hertfordshire is built-up, with the county becoming more rural in the north. Although the county is largely low-lying it does merge into the Chilterns in the west. The county is within the London commuter belt, with good transport links to the capital, although Hertfordshire has its own industry and agriculture is still important. There are a number of New Towns and Garden Cities. St Albans is known for its Roman remains.

Roads

Tunnel on the A505 Baldock bypass

Owing to its proximity to London, most traffic heading north from the capital has to pass through Hertfordshire; the A5 and A1 pass through the county, as does the original route of the A6 (although that road no longer exists south of Luton). As such, with a handful of exceptions (most notably the A414 and A505), the county's road network radiates out of London. However, some of the more minor Class II roads are remarkably narrow. The first roundabout in the country, Sollershot Circus, was built in Letchworth Garden City. Hertfordshire is in the debatable situation of having two downgraded motorways: the A10 (now A414) and A41(M) (now A41).

Most of the non-trunk roads in Hertfordshire are maintained by Hertfordshire County Council, although the area around Chipping Barnet is maintained by Barnet London Borough Council. Highways England maintain the main M25, M1 and A1/A1(M). The A5 is still trunk (although plans are underway to bypass this) and there are a couple of other trunk roads near St Albans. Part of the A1 is maintained by Transport for London, the only road in Hertfordshire under their control.

At one time the A5 and A6 cannoned off each other in the centre of St Albans but both roads have now been downgraded here.
