Welwyn Hatfield is a local government district in southern Hertfordshire, England.

Its comes from the two towns of Welwyn Garden City and Hatfield. Each of these towns have railway stations on the East Coast Main Line and being close to the A1 road.

Set within the London Green Belt , the towns retain something of their own identities although they clearly function, increasingly, as dormitories for householders who work in London. The Welwyn viaduct carries the railway mentioned above and is a locally important landmark that simultaneously represents a bottleneck restraining capacity over this strategic transport route. Several ideas to overcome this limitation without damaging its essential historic character and rhythmic design are periodically discussed.
